Frequently Asked Technical-Round Wipro Interview Questions for Freshers

The technical round in Wipro’s interview process is crucial for freshers as it dives deep into your core understanding of computer science concepts, programming skills, and problem-solving abilities. Interviewers use these questions to test theoretical knowledge and evaluate your practical approach to real-world technical problems. By familiarizing yourself with these questions and their underlying concepts, you’ll be well-equipped to confidently showcase a clear understanding of key technical principles.

Let’s have a look at some of the most common technical questions freshers encounter while interviewing at Wipro.

1. How would you connect one system to another without internet access?

Sample Answer

“To connect two systems without internet access, you can establish a connection using a local network. One way is through LAN (Local Area Network) using an Ethernet cable, where both systems are connected to a switch or router. Alternatively, for a wireless connection, you can use Wi-Fi Direct or Bluetooth. With Wi-Fi Direct, devices communicate directly with each other without the need for an intermediary router. Another option is using USB-to-USB cables or even a cross-over Ethernet cable for a direct connection, though this might require additional configuration depending on the operating system.”

2. Can you tell me something about the four fundamental principles of OOPs?

Sample Answer

“The four fundamental principles of Object-Oriented Programming (OOPs) are essential for designing and implementing software in an efficient, modular, and reusable manner:

• Encapsulation: This principle is about bundling data and the methods that operate on that data into a single unit or class. It helps protect the integrity of data by restricting direct access to some of an object’s components and instead providing controlled access through methods. For example, a bank account class might encapsulate the balance and only allow modifications through deposit or withdrawal methods, ensuring no illegal operations.
• Inheritance: Inheritance allows one class to inherit properties and behaviours (methods) from another class, fostering code reuse. A subclass can extend a parent class, inheriting all of its attributes and methods, and even override or extend them to suit its specific needs. For instance, a Car class can inherit from a generic Vehicle class, inheriting common properties like speed or fuel.
• Polymorphism: This principle refers to the ability of different classes to respond to the same method in different ways. It can be achieved through method overriding or method overloading. For example, a Shape class might have a method draw(), and different subclasses like Circle or Rectangle would implement their own version of draw().
• Abstraction: Abstraction hides the complex implementation details from the user and exposes only the necessary functionalities. This allows a programmer to work at a higher level of abstraction. For instance, when using a mobile phone, you don't need to understand how the touch screen works internally, just how to interact with it.

These principles help in creating modular, reusable, and maintainable code.”

3. What is method overloading? Is it the same as method overriding?

Sample Answer

“Method overloading occurs when multiple methods have the same name but different parameters (either in number or type) within the same class. The compiler differentiates them based on the method signature. For example, a class might have a method add(int a, int b) and another method add(double a, double b). Both methods perform the addition operation but on different types of data.

This is not the same as method overriding, which occurs when a subclass provides its own specific implementation of a method that is already defined in its superclass. Overriding methods must have the same method signature (name, return type, and parameters). For example, in a Dog class that extends an Animal class, you might override the makeSound() method to provide a dog-specific sound rather than using the generic method in the Animal class.”

4. What are dictionary attributes?

Sample Answer

“In programming languages like Python and JavaScript, dictionaries are data structures that store key-value pairs in a structured format. The keys are unique identifiers, and the values are the data associated with those keys, such as {'name': 'Preeti', 'age': 24}. Dictionary attributes refer to the various methods and operations that dictionaries support. 

• Dynamic Size: Dictionaries can grow and shrink dynamically, adapting to the needs of the program without any fixed size limit.
• Fast Lookups: They offer fast access to values using keys, with an average time complexity of O(1) for lookups, making them ideal for quick data retrieval.
• Nested Dictionaries: You can also have nested dictionaries, where a dictionary holds other dictionaries as values, allowing the creation of complex data structures, such as {'person': {'name': 'Preeti', 'age': 24}}.

Dictionaries allow for quick insertion and deletion based on keys, making them essential for scenarios where you need to associate specific data with unique identifiers. They also allow for efficient data storage, retrieval, and data management. For example, in Python, you can use methods like .keys() to retrieve all the keys in the dictionary, .values() to get all the values, and .items() to get both the keys and values as tuples.”

5. What is the use of the DCL language?

Sample Answer

“DCL or the Data Control Language is used in SQL to define access controls for database users. The two main DCL commands are GRANT and REVOKE. The GRANT command is used to assign specific privileges (like SELECT, INSERT, UPDATE, DELETE) to users on a database object, such as a table or a view. For example, you can grant a user the privilege to read from a table but not modify the data. The REVOKE command is used to remove those privileges. DCL plays a crucial role in database security, ensuring that only authorized users have access to certain data and operations.”

6. Can you tell me about the different sorting techniques?

Sample Answer

“There are several sorting algorithms, each with its own strengths and weaknesses depending on the data and context. Here are a few common ones:

• Bubble Sort: This is a simple sorting algorithm that repeatedly steps through the list, compares adjacent elements, and swaps them if they are in the wrong order. It continues doing this until the list is sorted. While easy to implement, its time complexity is O(n²), making it inefficient for large datasets.
• Selection Sort: In this algorithm, the list is divided into two parts: the sorted portion and the unsorted portion. It selects the smallest element from the unsorted part and swaps it with the first unsorted element. The process repeats until the list is sorted. Like bubble sort, its time complexity is O(n²).
• Insertion Sort: This algorithm builds a sorted list one item at a time by taking elements from the unsorted portion and inserting them into their correct position in the sorted portion. It works well for small datasets and has a time complexity of O(n²) in the worst case, but O(n) when the list is already sorted or nearly sorted.
• Merge Sort: A divide-and-conquer algorithm that divides the list into smaller sub-lists, sorts each sub-list, and then merges them to produce the sorted list. It has a time complexity of O(n log n), which makes it more efficient than O(n²) algorithms for large datasets.
• Quick Sort: Another divide-and-conquer algorithm that partitions the list into two smaller sub-lists based on a pivot element, sorts them recursively, and then combines the results. Quick sort has a time complexity of O(n log n) on average but O(n²) in the worst case if the pivot selection is poor.
• Heap Sort: This sorting algorithm is based on a binary heap data structure. It first builds a max-heap (or min-heap) and then repeatedly extracts the maximum element (or minimum element in a min-heap) to build the sorted list. Heap sort also has a time complexity of O(n log n), but it is less efficient in practice than quick sort.

These sorting algorithms are commonly used in different contexts based on the size and nature of the data being sorted.”

7. What is a stack? How is it different from a queue?

Sample Answer

“A stack is a linear data structure that operates on the Last In, First Out (LIFO) principle. This means the last element added to the stack is the first one to be removed. Imagine a stack of plates: the last plate you put on the top is the first one you'll take off. In a stack, you can only insert (push) and remove (pop) elements from the top of the stack.

On the other hand, a queue operates on the First In, First Out (FIFO) principle. This means the first element added to the queue is the first one to be removed. You can think of a queue as a line at a ticket counter – the first person in line is the first one to get served. 

The main difference between a stack and a queue is the order in which elements are processed: stacks remove the last element added, while queues remove the first element added.”

8. What is a tree? What are the different ways of traversing a tree?

Sample Answer

“A tree is a hierarchical data structure consisting of nodes connected by edges. Each tree has a single node called the root, and every other node is connected to it either directly or indirectly. Trees are used to represent structures like file systems, family trees, or and organizational charts, where each node may have multiple children but only one parent (except the root node).

There are several ways to traverse a tree, or visit each node:

• In-order Traversal: In this traversal, you visit the left subtree, then the root node, and finally the right subtree. This is one of the most commonly used traversals, especially in binary search trees (BST). When applied to a binary tree, in-order traversal visits nodes in ascending order of their values, making it especially useful when you want to retrieve sorted data from a binary search tree. 
• Pre-order Traversal: Here, the root node is visited first, followed by the left subtree and then the right subtree. This traversal is particularly useful when you need to create a copy of the tree or when you want to process the root before processing the children. For example, in a file system, pre-order traversal can help when you need to first access a directory before looking at the files and subdirectories inside it.
• Post-order Traversal: In this method, you visit the left subtree, then the right subtree, and finally the root node. This traversal is often used in situations where you need to delete nodes or perform a post-processing step. In a file system context, post-order traversal might be useful for deleting files or directories, ensuring that all files within a directory are deleted before the directory itself is removed.
• Level-order Traversal: In level-order traversal, also known as breadth-first traversal, nodes are visited level by level, starting from the root and moving across each level from left to right. This traversal is typically implemented using a queue and is useful when you need to visit all nodes at the same level before moving down to the next level. This is useful in situations where you want to process the nodes in layers, such as finding the shortest path in an unweighted graph or searching for nodes at a specific depth. 

Each traversal method serves different purposes depending on the problem at hand, and choosing the appropriate one can greatly affect the efficiency and outcome of an algorithm.”

9. What is a circular linked list? Explain its working.

Sample Answer

“A circular linked list is a variation of a linked list where the last node in the list points back to the first node, forming a loop. Unlike a regular linked list where the last node points to NULL, a circular linked list's tail node points to the head node, creating a continuous circular flow.

This structure is useful in scenarios where you need to loop through the list continuously without having to restart or reset the list. For example, circular linked lists are commonly used in applications like the implementation of round-robin scheduling in operating systems or in music playlist applications where the playlist repeats once the last song is reached.

To traverse a circular linked list, you start from the head node and continue to the next node until you reach the head node again, signifying the end of one complete circle.”

10. What are the different ways of decision making and conditional execution in programming languages?

Sample Answer

“In programming, decision making and conditional execution methods allow the program to choose among different actions based on specific conditions. The most common ways to perform decision-making and conditional execution include:

• If-Else Statements: The if-else statement is one of the most straightforward ways to control the flow of execution based on a condition. The if block is executed if the condition evaluates to True; if it evaluates to False, the else block is executed instead. This creates a simple, binary decision-making process. In more complex scenarios, there may be multiple conditions to check, and for this purpose, if-else can be nested, meaning that one if-else statement is placed inside another. The else part can also be followed by additional if conditions, creating an extended decision structure (often referred to as an if-elif-else chain).
• Switch-Case (or Match-Case in some languages): The switch or match statement is used when there are multiple possible conditions to check based on a single variable. Rather than writing many if-else statements, a switch statement provides a cleaner, more readable way to execute different code blocks depending on the value of an expression. Typically, in a switch block, each possible condition is checked (often referred to as a ‘case’), and if a match is found, the corresponding code block is executed. If no match is found, a default block of code can be executed. This approach is more efficient in cases where there are many possible conditions for the same variable.
• Ternary Operator: The ternary operator provides a shorthand way of writing an if-else statement in a single line. It is especially useful for simple conditions that assign a value to a variable based on the result of the condition. It follows the format of condition ? value_if_true : value_if_false. The operator is a compact way to express a basic conditional without the need for full if-else structures, making the code more concise and readable in certain situations.
• Nested Conditionals: Nested conditionals refer to using decision structures within other decision structures. For example, you might have an if statement inside another if statement. This allows more complex decision-making by evaluating multiple conditions at different levels. Nested conditionals are useful when the conditions need to be checked hierarchically. For instance, if one condition is true, the program can check for another condition, and so on, leading to more refined control over the flow of execution.
• Logical Operators (AND, OR, NOT): In decision-making, logical operators are often used to combine multiple conditions. These operators allow you to check if more than one condition is true, or if at least one of the conditions is true.
  
  • AND (&&): The condition only passes if both conditions are true.
  • OR (||): The condition passes if at least one of the conditions is true.
  • NOT (!): Reverses the result of a condition. If the condition is true, NOT will make it false and vice versa.

Using logical operators provides more flexibility when checking conditions, as you can combine multiple simple conditions into a single complex decision.

• Pattern Matching (Advanced Decision-making): Pattern matching is an advanced feature found in newer programming languages or recent versions of existing languages. It allows more complex and flexible decision-making by matching entire data structures, rather than just individual values. For example, in languages like Python (from version 3.10) or Scala, pattern matching allows the programmer to match not just the value of a variable but also the structure and type of data it contains, making decisions based on more complex conditions than what typical conditionals allow.

Each of these methods provides a unique way to control the flow of the program and guide the logic of the code effectively, making decisions based on different conditions.”

11. What is the basic function of a primary key?

Sample Answer

“A primary key is a unique identifier for each record in a database table. It ensures that no two rows in a table have the same values for the primary key column, thus maintaining the integrity of the data. For example, in a table storing employee details, the EmployeeID can serve as the primary key.

Additionally, the primary key helps to establish relationships between tables in a relational database. For instance, in an Orders table, the OrderID can act as a primary key that uniquely identifies each order, while foreign keys in other tables, like CustomerID, reference this key to link data across tables.”

12. Explain the concept of multitasking, multiprogramming, multithreading, and multiprocessing?

Sample Answer

“Multitasking refers to the ability of an operating system to run multiple tasks simultaneously by switching between them. For example, you can listen to music while browsing the internet. It's an illusion of parallel execution created by rapidly switching tasks on a single processor. Multiprocessing involves using multiple processors to execute different processes at the same time. This method allows for real parallelism, especially in multi-core systems, where each core executes a separate process concurrently. Multiprogramming is a method where multiple programs are loaded into memory at once, and the CPU executes them by switching between them. The goal is to keep the CPU busy by utilizing idle time while one program is waiting for input/output operations. Multithreading involves running multiple threads within a single program, where each thread represents a different task. Threads share the same memory space, and this allows tasks like downloading a file while updating the UI to run simultaneously.”

13. What is the Java Virtual Machine?

Sample Answer

“The Java Virtual Machine (JVM) is an abstract computing machine or virtual machine that enables a computer to run Java programs. It is responsible for converting Java bytecode into machine-specific code. When a Java program is compiled, the source code is converted into bytecode, which is platform-independent. The JVM then takes that bytecode and translates it into native machine code to be executed by the host machine. One of the most important features of the JVM is that it allows Java to be platform-independent, meaning that the same Java program can run on any system that has a JVM implementation, whether it’s Windows, macOS, or Linux. The JVM also manages memory through garbage collection, which automatically removes objects that are no longer needed, preventing memory leaks.”

14. What is JavaScript? Can you tell me some of its features?

Sample Answer

“JavaScript is a high-level, interpreted programming language primarily used for creating interactive effects within web browsers. It's a versatile language that can be used both on the client-side (in the browser) and server-side (through platforms like Node.js). Some key features of JavaScript include:

• Event-Driven Programming: JavaScript operates based on events, allowing the webpage to respond to user interactions like clicks, form submissions, or mouse movements in real time.
• Asynchronous Programming: JavaScript can handle tasks like fetching data from a server without freezing the page. This is made possible by features like Promises and async/await, ensuring that operations are non-blocking.
• First-Class Functions: Functions in JavaScript are first-class citizens, meaning they can be assigned to variables, passed as arguments, and returned from other functions.
• Dynamic Typing: JavaScript is loosely typed, meaning variables can hold different types of data (strings, numbers, objects) without explicitly declaring the type.
• Prototype-Based Inheritance: Unlike class-based inheritance in some other languages, JavaScript uses prototypes. This means objects can inherit properties and methods from other objects.

JavaScript is most crucial for front-end development, enhancing user experience and interactivity.”

15. Do you know what synchronization means in Java?

Sample Answer

“In Java, synchronization is a mechanism used to ensure that only one thread can access a resource at a time, preventing issues such as data inconsistency or race conditions. It is particularly useful when multiple threads are working with shared data, and you want to avoid conflicts where two threads modify the same data simultaneously.

Java provides several ways to synchronize code:

• Synchronized Methods: By marking a method with the synchronized keyword, it ensures that only one thread can execute it at any given time for an object.
• Synchronized Blocks: A more granular approach where only specific blocks of code are synchronized, allowing greater flexibility and potentially better performance compared to synchronizing entire methods.
• Locks: The java.util.concurrent.locks package offers more advanced synchronization techniques through lock objects, which provide more control over thread synchronization and allow features like try-lock and timed locks.

Synchronization ensures thread safety, but it can impact performance if not managed properly, as it may cause threads to wait for others to release the lock.”

16. State some uses of the super keyword in Java?

Sample Answer

“In Java, the super keyword is used to refer to the immediate parent class. It has several key applications in object-oriented programming:

• Accessing parent class methods: If a subclass overrides a method of its superclass, you can use super to call the parent class’s version of the method, ensuring that you don’t accidentally bypass the parent’s functionality. For example, super.someMethod().
• Accessing parent class constructors: You can use super() to call the parent class constructor. This is especially useful when the parent class has a parameterized constructor that needs to be invoked from the subclass. If no constructor is explicitly called, the default constructor of the parent is called automatically.
• Accessing parent class fields: You can access fields in the parent class that have been hidden by subclass fields. For instance, if you have a field with the same name in both the superclass and subclass, super.fieldName can be used to access the parent class’s version.

The super keyword also maintains inheritance relationships between classes, making the code cleaner and easier to understand.”

17. How is StringBuilder different from StringBuffer in Java?

Sample Answer

“Both StringBuilder and StringBuffer are used to handle mutable strings in Java, but they differ in terms of thread safety and performance:

• Thread Safety: StringBuffer is thread-safe because its methods are synchronized, meaning only one thread can access the data at a time. This makes StringBuffer useful in a multi-threaded environment where you need to ensure that one thread does not interfere with another. However, this comes at the cost of performance.
• Performance: StringBuilder, on the other hand, is not synchronized and thus not thread-safe. However, this lack of synchronization makes StringBuilder faster than StringBuffer when used in single-threaded applications or when thread safety is not a concern. This makes StringBuilder the preferred choice for most applications.

In summary, use StringBuffer when thread safety is a priority, and opt for StringBuilder when performance is more important, especially in single-threaded scenarios.”

18. What is a destructor? Do C++ and Java have a destructor?

Sample Answer

“A destructor is a special method used to clean up or release resources that were allocated to an object when it is destroyed. Destructors are important for freeing memory or closing file handles, network connections, and other resources. Destructors are automatically called in C++ when an object goes out of scope or is deleted. A C++ destructor is defined by a method with the same name as the class but preceded by a tilde (~). C++ requires destructors to manually manage memory allocation and deallocation, especially when working with dynamic memory.

On the other hand, Java does not have destructors in the traditional sense. Instead, Java uses garbage collection to automatically reclaim memory used by objects when they are no longer referenced. However, Java does provide a finalize() method (which is rarely used nowadays) to perform cleanup operations before an object is garbage collected. It's worth noting that finalize() is not guaranteed to be called and is considered deprecated in some cases.”

19. Do you know about Java’s order of precedence and associativity? How is it used?

Sample Answer

“Java follows a set of rules called operator precedence to determine the order in which operators are applied in expressions. Naturally, operators with higher precedence are evaluated before operators with lower precedence. When two operators have the same precedence, associativity determines the order in which they are evaluated.

• Precedence: For example, multiplication (*) has higher precedence than addition (+), so in the expression 3 + 5 * 2, the multiplication is performed first, yielding 3 + 10 = 13.
• Associativity: If operators have the same precedence, associativity determines whether the expression is evaluated left to right (left-associative) or right to left (right-associative). For example, the = operator in Java is right-associative, so in a = b = c = 10, the assignment happens from right to left, with c being assigned 10 first, followed by b and a.

Understanding operator precedence and associativity is crucial for writing correct expressions and avoiding logic errors.”

20. What are some major differences between Java and SQL?

Sample Answer

“Java and SQL are both powerful tools in the programming world, but they serve entirely different purposes and function in different ways:

• Purpose: Java is a general-purpose, object-oriented programming language used for creating applications, both for desktops and servers. It is used for developing business logic, handling events, and interacting with other applications. On the other hand, SQL is a domain-specific language used for managing and manipulating relational databases, specifically for querying, updating, and managing data stored in databases.
• Execution: Java programs are compiled into bytecode, which is then executed by the Java Virtual Machine (JVM) on different platforms. SQL is executed directly against a database management system (DBMS), which processes the commands and returns results based on the data stored in the database.
• Data Handling: Java can interact with a variety of data types and can work with multiple databases, performing complex operations and transformations. SQL, however, is focused on querying and manipulating data, and it supports operations like SELECT, INSERT, UPDATE, DELETE, and database schema management.

In summary, Java is used to develop applications, while SQL is used for managing and querying databases.”

21. Are errors and exceptions in Java the same thing?

Sample Answer

“No, errors and exceptions are not the same in Java. An error is typically a problem that is outside the control of the program, often related to the environment the program is running in, such as hardware failure or JVM issues. These errors usually indicate serious problems that are not meant to be handled by the program itself. On the other hand, an exception is an event that disrupts the normal flow of the program and can usually be handled by the program using try-catch blocks. Exceptions are caused by the program’s logic and can be anticipated and handled with proper error-handling mechanisms to avoid crashing the program.”

22. What is the SQL Server Profiler?

Sample Answer

“The SQL Server Profiler is a tool provided by Microsoft SQL Server that helps in monitoring, analyzing, and recording SQL Server events in real-time. It captures various events related to SQL queries, transactions, server performance, and errors. This tool is useful for database administrators and developers to troubleshoot performance issues, identify slow-running queries, and optimize SQL code. By analyzing the captured data, one can pinpoint bottlenecks, deadlocks, and other issues, improving the overall performance and stability of the database system.”

23. How are TRUNCATE, DROP, and DELETE commands in SQL different from each other?

Sample Answer

“The DELETE command removes a table’s rows one by one and logs each row deletion. It can be rolled back if wrapped in a transaction and can also include a WHERE clause to delete specific rows. The TRUNCATE command, on the other hand, is used to remove all records from a table but does not log individual row deletions, making it faster than DELETE. It also resets identity columns to their seed value. However, it is not transactional, meaning once you execute it, the data cannot be recovered unless you have a backup. Conversely, DROP is used to remove an entire table (or database, or other objects) from the database. Unlike TRUNCATE and DELETE, it also removes the structure of the table, meaning you can no longer use the table even though the data is gone.”

24. What is the difference between public, void, and static?

Sample Answer

“In Java, public is an access modifier that makes a class, method, or variable accessible from any other class. When you declare a method as public, it can be called from other classes in any package. Void, on the other hand, is a return type used in methods to indicate that the method does not return any value. For example, a method with a void return type performs an action but doesn’t send any data back to the caller. Static is a keyword used to declare class-level variables or methods, meaning they belong to the class rather than to instances of the class. Static members are shared across all instances of the class and can be accessed without creating an object.”

25. How is free() different from delete() in C++?

Sample Answer

“In C++, free() is a function used to deallocate memory that was previously allocated using the malloc() or calloc() functions in C++. It works with memory that was dynamically allocated from the heap, but it doesn't call any destructor methods or handle object cleanup. delete(), on the other hand, is specifically used to deallocate memory that was allocated using new. It not only frees the memory but also calls the destructor of the object, making it safer when dealing with objects that require resource management (like closing file handles or releasing memory for pointers to other resources). So, free() is used for C-style memory management, while delete() is part of C++'s object-oriented memory management system.”

26. In C++, what are precondition and postcondition to a member function?

Sample Answer

“In C++, preconditions are the conditions that must be true before a function is called, essentially specifying the state that the program or the data should be in for the function to work correctly. For example, if you're writing a function to divide two numbers, a precondition might be that the denominator should not be zero. Postconditions, on the other hand, are the conditions that should be true after the function has executed. They specify what the function guarantees to accomplish. For example, in the same division function, a postcondition might be that the result of the division is stored correctly. Using preconditions and postconditions helps in ensuring the correctness of the code and maintaining the program's integrity.

27. Explain memory management in the C language.

Sample Answer

“Memory management in C involves the allocation and deallocation of memory during the execution of a program. In C, memory is allocated using functions like malloc(), calloc(), and realloc() for dynamic memory allocation, and it is deallocated using free(). The malloc() function allocates a block of memory of a specified size and returns a pointer to it, while calloc() allocates memory for an array of elements and initializes them to zero. realloc() changes the size of a previously allocated memory block. It's important to ensure that memory is properly freed after use to prevent memory leaks, which can lead to increased memory usage and slow performance. Careful management of memory in C is essential since there is no automatic garbage collection, unlike in some higher-level programming languages.”

28. What is the purpose of using Python as a programming language?

Sample Answer

“Python is chosen by developers because it strikes a great balance between simplicity and power. Even for someone new to programming, Python’s syntax is very intuitive and closely resembles natural English, making learning and debugging much easier. 

Some reasons why I personally like working with Python are:

• Versatility across Paradigms: Python’s versatility is huge – it supports different programming paradigms like procedural, object-oriented, and functional programming, allowing developers more flexibility.
• Huge Library Support: Python is packed with extensive libraries and frameworks such as Pandas, NumPy, TensorFlow, and Django that save a lot of time and effort.
• Versatility of Use: It’s used in web development, data science, automation, machine learning, and even game development.
• Strong Community: Python has a large, active developer community constantly contributing tutorials, packages, and frameworks, which helps beginners and professionals alike.
• Cross-Platform Compatibility: Python code runs smoothly across Windows, macOS, and Linux without much tweaking.

All these factors make Python an ideal language for both beginners and experienced developers.”

29. Tell me something about the access modifiers in Python.

Sample Answer

“Python does support access modifiers, though not in the same strict way as languages like Java or C++. Unlike other languages, Python doesn't enforce access control with keywords like public, private, or protected. Instead, access control is more of a naming convention than a rule, but it still helps organize code well.

Here are the types:

• Public: Any variable or method that doesn’t start with an underscore is considered public by default and can be accessed from anywhere.
• Protected: When an attribute, variable or method is prefixed with a single underscore (e.g., _variable), it signals that it’s meant for internal use to be used only within the class or its subclasses. signaling developers to avoid direct access.
• Private: Prefixing a method or variable with two underscores (__variable) makes it private. This triggers name mangling, where Python internally changes the name to make accidental external access difficult.

However, these are only conventions; Python trusts the developer to follow them responsibly. If needed, attributes can still be accessed directly, but it’s discouraged because it breaks encapsulation principles.”

30. Can you tell me a few advantages of using DBMS?

Sample Answer

“A Database Management System (DBMS) offers a structured and efficient way of handling large amounts of data, especially compared to flat files. Some of its key advantages include:

• Data Consistency and Integrity: DBMS enforces data integrity by applying validation rules and constraints, ensuring data remains accurate, consistent, and reliable.
• Concurrent Access: Thanks to transaction management and locking mechanisms, DBMS centralizes data storage so multiple applications and users can access and manipulate the data simultaneously without duplication or inconsistency. 
• Data Security: With user authentication, role-based access controls, and encryption, DBMS safeguards sensitive data against unauthorized access. 
• Backup and Recovery: Most DBMSs come with built-in tools for automated backups and restoration in case of errors or hardware failures, reducing data loss risk.
• Improved Data Sharing: DBMS facilitates easy data sharing across applications and users within an organization.
• Reduced Redundancy: Through normalization and relational design, DBMS maintains a single source of truth and eliminates duplicate data.

These features are why almost every modern application uses some form of a DBMS.”

31. What are the different types of objects in a DBMS?

Sample Answer

“In a DBMS, we work with various types of database objects that help store, retrieve, organize, and manipulate data efficiently. The most common ones include:

• Tables: These are the core structures where data is stored in rows and columns.
• Views: Views act like virtual tables, based on the result of SQL queries, that show a filtered or joined subset of data without storing it physically but displaying it from underlying tables.
• Indexes: Much like an index in a book, these are special lookup structures that speed up query processing and data retrieval by creating quick access points to records.
• Stored Procedures: These are precompiled SQL code blocks saved in the database that can be reused to perform complex operations like insertions or calculations. 
• Functions: Similar to stored procedures, functions return a single value and can be used in SQL expressions.
• Triggers: Set rules that automatically execute predefined actions (like inserting a log) in response to certain database events like insert, update, or delete on tables. These help maintain data consistency and enforce business rules.
• Schemas: Schemas are logical containers that group related database objects under a single namespace for organization and access control.

All of these objects work together to keep the data well-structured, secure, and easily accessible.”

32. What are the ACID properties of a DBMS?

Sample Answer

“ACID properties define the key guarantees a DBMS provides to ensure reliable and robust transaction management. Here's what each of them means:

• Atomicity: This ensures that a transaction is treated as a single unit, meaning every transaction is ‘all or nothing’ – if any part fails, the whole transaction is rolled back, so partial changes never corrupt the database. For example, if money is deducted from one account but not credited to another, the entire transaction should be rolled back.
• Consistency: This ensures that every transaction moves the database from one valid state to another. This means the database still adheres to all rules, constraints, and triggers defined on the data.
• Isolation: Isolation makes sure transactions run independently without interfering with each other, even if multiple transactions execute concurrently. Each one should behave as if it’s the only transaction happening. This prevents issues like dirty reads or lost updates.
• Durability: This guarantees that once a transaction is committed, its changes are permanent, all thanks to proper logging and backup mechanisms. This means that the data remains secure even in case of a system crash or power failure. 

These four principles ensure data integrity and trustworthiness, especially in multi-user environments.”

33. Do you know about the three levels of abstraction in a DBMS?

Sample Answer

“Yes, I do. The three levels of abstraction are part of the Three-Level Architecture proposed by ANSI/SPARC. It helps separate user interaction from the complex inner workings of a database. The three levels are:

• Internal Level (Physical Level): This is the lowest level and deals with the actual physical storage of data on hardware. This includes file structures, indexing methods, and storage details that users don’t need to worry about.
• Conceptual Level (Logical Level): This provides a community user view, meaning it defines what data is stored, its structures, and the relationships between them. It hides details of the physical storage. For example, how tables relate to each other or what fields they contain.
• External Level (View Level): This is the highest abstraction level which represents how users or applications see the database. Each user has a different view of the data, often simplified or tailored for their specific needs, without exposing the full database schema or internal complexity.

This layered approach adds flexibility, simplifies data access, and enhances security by limiting what users can see and interact with.”

34. What are the different types of shells in Linux?

Sample Answer

“Linux offers multiple shells, which are command-line interpreters that allow users to interact with the operating system. These shells are optimized for specific tasks and user preferences. 

• Bourne Shell (sh): This classic Unix shell, known for its simplicity and scripting capabilities, remains POSIX-compliant and lightweight. It’s faster and more preferred for system scripts and embedded environments.
• Bourne Again Shell (bash): The default and most widely used shell is known for its powerful scripting capabilities, ease of use, and wide adoption across Linux distributions. It also supports command history, tab completion, and job control. 
• Z Shell (zsh): This Unix shell builds on the Bourne Again shell, adding spell correction, theme and plugin support via Oh My Zsh framework to improve productivity, and shared command history across sessions. It is highly customizable and also supports advanced tab completion.
• C Shell (csh): This Linux shell mirrors the syntax of the C programming language with the idea to improve interactive use. It is highly useful for users familiar with C programming and supports user-defined aliases, built-in expression grammar, and scripting. C shell has improved readability and performance compared to the Bourne shell.
• KornShell (ksh): This shell combines the features of Bourne and C shells and aims to focus on both interactive commands and programming features. It also emphasizes performance with associative arrays, built-in arithmetic, advanced scripting capabilities, and advanced looping constructs for enterprise-grade scripts
• Friendly Interactive Shell (fish): This user-friendly Unix shell focuses on out-of-the-box usability. The feature-rich shell does not require additional configuration and provides autosuggestions, syntax highlighting, simplified scripting, and sane defaults

I determine which shell to use for my scripting workflow based on each shell’s strengths.”

35. What are the three main types of cloud computing?

Sample Answer

“Cloud computing services break down into three core models that address distinct business needs. The three primary cloud computing models are:

• Infrastructure as a Service (IaaS): IaaS provides on-demand virtualized computing resources over the internet. Users can rent servers, storage, and networking components, allowing for scalable and flexible infrastructure management without being bogged down by physical hardware management.
• Platform as a Service (PaaS): PaaS offers an application framework and development environment in the cloud, allowing customers to develop, run, and manage applications without dealing with the underlying infrastructure. Instead, the provider handles OS, middleware, and runtime dependencies. It streamlines the development process by providing tools and frameworks.
• Software as a Service (SaaS): SaaS delivers fully functional software applications over the internet on a subscription basis. Users can access applications via web browsers or thin clients with the vendor managing all backend operations, updates, and security. SaaS eliminates the need for installations or maintenance.

By mixing and matching IaaS, PaaS, and SaaS, businesses achieve flexibility, faster time-to-market, and cost efficiency aligned with their strategic priorities.”

36. What benefits do hybrid clouds have in the world of cloud computing?

Sample Answer

“Hybrid clouds combine public and private cloud services, offering several advantages:

• Ease of Use: Hybrid clouds enable consistent application architectures and management tools across both realms, simplifying operations and speeding development cycles. 
• Flexibility and Scalability: Organizations can scale resources up or down based on demand, optimizing costs and performance.
• Disaster Safety: This approach also supports a phased cloud adoption strategy, letting teams move non-critical functions first and sensitive operations later, reducing migration risks. 
• Enhanced Security: Sensitive data can be kept on-premises or in private clouds, while less critical workloads run in the public cloud. This ensures regulatory compliance and tighter access controls, balancing security and efficiency.
• Cost Management: During traffic spikes or heavy compute needs, workloads seamlessly burst into public clouds, so businesses pay only for incremental resources when required. 
• Business Continuity: Hybrid clouds provide business continuity through multi-site redundancy and have built-in disaster recovery and backup solutions, ensuring minimal downtime and data loss.

This approach allows businesses to leverage the benefits of both private and public clouds effectively.”

37. Do you know what a virtual private cloud is?

Sample Answer

“A Virtual Private Cloud (VPC) is an isolated virtual network within a public cloud provider’s infrastructure. It gives businesses dedicated IP ranges, subnets, routing tables, and security groups that function as if they owned a private datacentre in the cloud. They can segment workloads into public and private subnets, applying fine-grained access controls to limit internet exposure. Virtual Private Clouds allow organizations to:

• Define Custom Network Configurations: Users can set up subnets, route tables, and gateways tailored to their specific needs.
• Enhance Security: Businesses retain full control over network topology, gateway appliances, and firewall rules, enabling them to comply with strict corporate security policies.
• Maintain Control: VPCs allow businesses to capture IP traffic details and manage IP address ranges for monitoring, auditing, and troubleshooting.

VPCs provide the benefits of a private cloud while utilizing the scalability of public cloud services.”

38. What is EUCALYPTUS in cloud computing? List some of its capabilities.

Sample Answer

“EUCALYPTUS (Elastic Utility Computing Architecture for Linking Your Programs to Useful Systems) is an open-source Linux-based software platform that enables organizations to build AWS-compatible private and hybrid clouds on existing hardware. Some of its important capabilities include:

• IaaS Implementation: EUCALYPTUS provides Infrastructure as a Service, enabling the creation of virtual cloud infrastructure and helping users manage Compute, Storage, and networking resources.

39. What are the four pillars of API?

Sample Answer

“Designing and managing a production-grade API requires attention to four essential pillars – Scalability, Security, Performance, and Usability:

• Scalability: Scalability ensures your API can handle exponential traffic growth by leveraging horizontal scaling, stateless architecture, and efficient caching strategies; all without performance degradation.
• Security: Security refers to protecting data and services from unauthorized access through strong authentication (OAuth 2.0, JWT), authorization controls, and end-to-end encryption (TLS), plus rate limiting to thwart abuse.
• Performance: Performance focuses on delivering fast and reliable resources, minimizing latency, and optimizing resource usage for a high throughput through techniques like payload compression, CDN distribution for static assets, and asynchronous processing for time-consuming tasks. 
• Usability: Lastly, usability emphasizes on providing a developer-friendly interface through clear, consistent endpoint naming, consistent design, versioning strategies, and comprehensive documentation with examples, SDKs, and interactive sandboxes.

Together, these pillars help developers integrate their API rapidly, deploy clients confidently, and maintain service reliability. These pillars lead to robust, secure, and efficient APIs that enhance user experience and system integration.”

40. How is an HTML block-level element different from an inline element?

Sample Answer

“In HTML, elements are categorized based on their display behaviour. Block-level elements, such as <div>, <section>, <p>, and <h1>, occupy the full width available, stretching from left to right, and always start on a new line. This behaviour allows them to stack vertically, creating distinct sections on a webpage. In contrast, inline elements like <span>, <a>, and <strong> only take up as much width as their content requires and do not start on a new line. They flow within the content, allowing other inline elements to sit beside them on the same line. 

Inline elements are used to style or manipulate parts of text within block elements. So, block elements structure the layout, while inline elements work within that structure without breaking it. Understanding this difference is crucial for web design and helps in creating layouts that are both functional and aesthetically pleasing.”

41. What is Application Development Framework? What are the key components in ADF?

Sample Answer

“An Application Development Framework, or ADF, is a set of pre-built tools and libraries that especially streamlines the development of enterprise applications. It provides a structured approach to building applications, promoting reusability, and reducing development time. For instance, Oracle’s ADF is a comprehensive framework that simplifies Java EE development by integrating UI, business services, and data control layers.

The key components of an ADF include:

• ADF Business Components: Pre-built application objects based on Java EE design patterns that simplify the modelling and maintenance of high-performance, complex, and database-centric services.
• ADF Faces: A rich set of JSF-based UI components that support AJAX and provide a dynamic user experience.
• ADF Controller: A crucial component that manages the flow of the application, handling navigation, state management, and task flow.
• ADF Model: The central part that acts as the middle layer, implements data controls and data bindings, and connects the UI elements to the business services.

By leveraging these components, developers can create robust, scalable, and maintainable applications efficiently, adhering to best practices and design patterns.”

42. If your system restarts repeatedly, how would you troubleshoot the issue?

Sample Answer

“When a system restarts repeatedly, it's essential to approach the issue methodically to identify the root cause. First, I'd look into system logs (like Windows Event Viewer or dmesg in Linux) to check for any error patterns or crash reports. I would then disable the automatic restart feature to capture any specific error messages that might appear during the reboot cycle. 

Next, I would check for overheating by monitoring the CPU temperature and inspect the power supply unit for any signs of failure, as these can cause the system to shut down abruptly to prevent damage. Additionally, I will run memory diagnostics to check for faulty RAM, which can also cause random restarts.

If the hardware seems fine, I will update all drivers, especially graphics and chipset drivers, as outdated or corrupt drivers can lead to system instability. Additionally, I’ll run an antivirus software to scan for malware that might be affecting system performance. If the issue still persists, I’ll boot into Safe Mode (the previous stable state) or reinstall the operating system to eliminate software-related problems. 

This systematic approach usually helps me identify whether it’s a hardware, OS, or driver-related issue. If I suspect any hardware issue, I’ll also consult a professional technician for further diagnosis and repair.”

43. What is a CSS preprocessor? Why is it used?

Sample Answer

“A CSS preprocessor is a scripting language that extends the capabilities of CSS, introducing features like variables, nesting, mixins, and functions. These features allow developers to write more structured, maintainable, and scalable stylesheets. Popular CSS preprocessors include Sass, LESS, and Stylus. These tools are compiled into standard CSS before being applied to the webpage, ensuring compatibility with all browsers. 

Instead of writing repetitive CSS, developers can use variables for colors or fonts, nest selectors for better readability, create reusable code blocks (mixins), and facilitate dynamic calculations (functions). The preprocessor then compiles this enhanced syntax into standard CSS that browsers understand. 

By using a preprocessor, developers can adhere to the DRY (Don't Repeat Yourself) principle, leading to cleaner and more efficient code. Utilizing a CSS preprocessor enhances productivity, reduces errors, and simplifies the maintenance of complex stylesheets, making it a valuable tool in modern web development. In my opinion, preprocessors save a lot of time and reduce repetition, especially when working on scalable web applications.”

44. Can you tell me something about RAID in the context of project management?

Sample Answer

“In project management, RAID is an acronym that stands for Risks, Assumptions, Issues, and Dependencies. It's a framework used to identify and manage these four critical elements throughout the project lifecycle.

• Risks: Risks are potential events or conditions that could negatively impact the project's objective, timeline, or budget. Identifying risks early allows for the development of mitigation strategies.
• Assumptions: Assumptions are factors that are considered true for the planning purpose but require proper validation, such as resource availability or stakeholder support. Documenting assumptions helps in understanding their impact on the project.
• Issues: Current problems that need to be addressed immediately to keep the project on track are called issues. Managing issues promptly prevents them from escalating.
• Dependencies: Lastly, dependencies are the relationships between tasks or deliverables that affect their sequencing. These inherently refer to tasks that rely on something else being completed first. Recognizing dependencies ensures that the project schedule is realistic and achievable.

I used a RAID log during a final-year group project to proactively address challenges and communicate effectively with stakeholders. It really enhanced decision-making and supported my project objectives.”

45. What is time slicing in CPU Scheduling? Tell me a few of its advantages.

Sample Answer

“Time slicing, also known as Round Robin scheduling, is a CPU scheduling technique where each process is assigned a fixed time slot or quantum during which it can execute. The CPU cycles through processes, allocating each one its time slice in turn. If a process doesn’t finish in its time slice, it gets moved to the back of the queue and waits for the next turn. This approach ensures that all processes receive an equal share of the CPU's time, promoting fairness and responsiveness in a multitasking environment. 

Some of its key advantages include:

• One of the primary advantages of time slicing is its simplicity and ease of implementation, making it suitable for general-purpose systems. 
• Time slicing allows real-time applications to maintain better control over execution timing.
• It also prevents any single process from monopolizing the CPU, enhancing system responsiveness, especially for shorter tasks. 
• Additionally, time slicing supports multitasking by allowing multiple processes to progress concurrently, improving overall system throughput. 

I find this method particularly interesting because it models the way most modern operating systems handle multitasking for users.”

‍

Now that you've gotten a good sense of the technical expectations, let's explore some logical reasoning questions that are commonly asked in Wipro interviews for freshers.

Logical Reasoning Wipro Interview Questions for Freshers

Logical reasoning is a critical component of Wipro's recruitment process. The company assesses your analytical thinking, problem-solving abilities, and cognitive skills through various reasoning questions. Often appearing in the online assessment, these questions can sometimes be asked during the face-to-face interview as well. Therefore, preparing for them thoroughly is as important as brushing up your technical knowledge.

For your ease, we’ve compiled a list of a few logical reasoning questions that have been asked by Wipro interviewers in the past.

1. You have two candles of equal size, each of which can burn for 1 hour. You also have a lighter, but there is no scale or clock. How would you measure 45 minutes using these candles?

Solution

“I will light the first candle at both ends simultaneously and the second candle at only one end at the same time. Since the first candle is lit from both ends, it will burn twice as fast as usual and will be completely burnt in 30 minutes. When the first candle finishes burning (after 30 minutes), I will immediately light the other end of the second candle. 

The second candle, initially burning from one end, now is burning from both ends. Since it had been burning from one end for 30 minutes, half of it was burnt, and half remained. Lighting the other end now makes the remaining half burn twice as fast, so it will take 15 minutes to finish. This way I will have measured 45 minutes in total.”

2. You have a birthday cake that needs to be cut into eight equal portions to serve seven of your friends and yourself. However, you’re only allowed to make three cuts. How do you accomplish this?

Solution

“I will first slice the cake horizontally through the center, dividing the cake into two equal halves (top and bottom layers). Next, I will make a vertical cut straight down the middle, dividing the cake into two halves, each with two layers now. Lastly, I will make another vertical cut perpendicular to the second cut, dividing the cake further into quarters. Because the cake was cut horizontally first, I will have two layers stacked, so the three cuts result in 8 equal pieces (4 pieces per layer × 2 layers = 8 pieces). This will divide the cake into eight equal pieces.”

3. Geetika has three daughters, Nupur, Komal, and Pragya. Her friend, Daksh, wants to know the ages of the girls. Geetika says the product of her girls’ ages is 72 and the sum of their ages is the same as her house number. Daksh still isn’t able to guess so Geetika gives him the third and final hint that her oldest daughter likes vanilla cheesecake very much, and with this Daksh instantly knows their ages. What are the ages of the three girls?

Solution

“To find the ages of the three girls, I will first find all possible triplets of positive integers whose product is 72, and calculate what their sum is. 

Since Daksh couldn't deduce the ages from the sum alone, the sum must correspond to more than one triplet. Checking the sums, the only repeated sum is 14 (triplets 2, 6, 6 and 3, 3, 8). The final clue states the oldest daughter likes cheesecake. This means there is a distinct oldest child, ruling out (2, 6, 6) because it has twins (two six-year-olds). Therefore, the ages of the Geetika’s girls are 3, 3, and 8 years old.”

4. You arrive at a fork in the road. One path leads to heaven, and the other leads to hell. There are two guards: one always tells the truth, and the other always lies. You don't know which guard is which. You can ask only one question to one guard. What question do you ask to determine the path to heaven?

Solution

“The classic solution is to ask a question that forces both guards to give the same answer, revealing the correct gate. I will ask either guard:

‘If I asked the other guard which gate leads to heaven, what would he say?’

If I asked the truthful guard, he would tell me the lie that the other guard would say (which would be the wrong gate). However, if I asked the lying guard, he would lie about the truthful guard’s correct answer, also pointing to the wrong gate. In both cases, the guard would indicate the wrong gate, so I will choose the opposite gate. This logic works because the double-layered question neutralizes lying and truth-telling.”

5. Three horses stand at the vertices of a triangle. Each horse randomly chooses a direction along the triangle’s edges to trot (either clockwise or counterclockwise). Find the probability that at least two horses collide.

Solution

“Each horse has 2 possible directions: clockwise (C) or counterclockwise (CC). Therefore, the total possible direction combinations = 2³ = 8. 

Creating all possible combinations, I find:

1. C, C, C — All clockwise → no collision (horses move in same direction)
2. C, C, CC — Two clockwise, one counterclockwise → collision occurs
3. C, CC, C — collision
4. C, CC, CC — collision
5. CC, C, C — collision
6. CC, C, CC — collision
7. CC, CC, C — collision
8. CC, CC, CC — all counterclockwise → no collision

Since, out of the 8 total outcomes, only cases 1 and 8 avoid collision, the number of no collision outcomes is 2. Therefore, the probability of no collision becomes 2/8 = ¼.

Now, calculating the probability that two or more horses collide, I find, 

P = 1 - 14=34=0.75 or 75% 

Thus, there is a 75% chance that at least two horses collide.”

As you prepare for the next stage of the interview process, it's essential to focus on coding-based Wipro interview questions for freshers.

Coding-Based Wipro Interview Questions for Freshers

The coding round is a critical phase in Wipro’s fresher recruitment process. It is designed to assess your ability to solve real-world problems using programming languages like C, C++, Java, or Python. This round evaluates not just your coding skills but also your logical thinking, algorithmic efficiency, and command over data structures. Wipro places strong emphasis on writing clean, optimized, and bug-free code.

Let’s quickly delve into some of the most commonly asked coding questions that freshers face during their Wipro interviews.

1. Write a program in C++ to reverse a given string.

Sample Answer

“Reversing a string involves accessing its characters from the end to the beginning and outputting them in that reverse order. The string is essentially an array of characters indexed from 0 to length-1. I start the process by determining the length of the string, which helps me identify the last character’s index. Then, using a loop, I traverse the string backward starting from the last character down to the first. For each iteration, I print or store the character at the current index. I also make sure to carefully use input functions like getline() in C++ to handle special cases like empty strings or strings with spaces.

Here is the final code for it:

#include <iostream>

#include <string>

using namespace std;

int main() {

    string str;

    cout << "Enter a string: ";

    getline(cin, str);

    int n = str.length();

    for (int i = n - 1; i >= 0; i--) {

        cout << str[i];

    }

    cout << endl;

    return 0;

}

This process inverts the order of characters, producing the reversed string.”

2. Write a program in Java to find the Fibonacci series up to the nth term.

Sample Answer

“The Fibonacci sequence is a series where each number is the sum of the two preceding ones, typically starting with 0 and 1. To generate this series up to the nth term, I will begin with two initial variables representing the first two numbers. In each iteration, I’ll print the current number and compute the next number by adding the two previous numbers. After this, I’ll update the variables to move forward in the sequence. This can be implemented iteratively or recursively, but I prefer iterative because of its efficiency. 

Here is the final code for it:

import java.util.Scanner;

public class FibonacciSeries {

    public static void main(String[] args) {

        Scanner sc = new Scanner(System.in);

        System.out.print("Enter the number of terms: ");

        int n = sc.nextInt();

        int a = 0, b = 1;

        System.out.print("Fibonacci Series: ");

        for (int i = 1; i <= n; i++) {

            System.out.print(a + " ");

            int next = a + b;

            a = b;

            b = next;

        }

        sc.close();

    }

}

The loop runs ‘n’ times, producing n terms of the series.”

3. Write a C++ program to find the power of a number using the recursion method.

Sample Answer

“Calculating the power of a number (base^exponent) recursively involves reducing the problem into smaller subproblems. The recursive function calls itself with the exponent reduced by 1 until it reaches the base case where the exponent is zero, which by definition returns 1. For every recursive call, the function multiplies the base number by the result of the function called with a decremented exponent. This process effectively breaks down the exponentiation into repeated multiplication. Recursion simplifies the loop construct by expressing repetition as function calls. Each call waits for the result of the next call, building up the multiplication chain.

Here is the final code for it:

#include <iostream>

using namespace std;

int power(int base, int exp) {

    if (exp == 0)

        return 1;

    return base * power(base, exp - 1);

}

int main() {

    int base, exponent;

    cout << "Enter base and exponent: ";

    cin >> base >> exponent;

    cout << base << "^" << exponent << " = " << power(base, exponent) << endl;

    return 0;

}

This code will generate the power of any given number.”

4. Write a program in Python that employs binary search to search for a given number in a sorted array of numbers.

Sample Answer

“Binary search is an efficient algorithm to find an element’s position in a sorted array by repeatedly dividing the search interval in half. Initially, two pointers represent the start and end indices of the array. I’ll calculate the middle element and compare it to the target value. If the middle element matches the target, the search ends successfully. If the target is less than the middle element, I’ll continue my search in the left half; if more, I’ll continue it in the right half. This halves my search space with each iteration, reducing time complexity to O(log n). I’ll repeat this process until the element is found or the search interval becomes empty, indicating the element is not present. 

Here is the final code for it:

def binary_search(arr, target):

    low, high = 0, len(arr) - 1

    while low <= high:

        mid = (low + high) // 2

        if arr[mid] == target:

            return mid

        elif arr[mid] < target:

            low = mid + 1

        else:

            high = mid - 1

    return -1

# Example usage

sorted_arr = [1, 3, 5, 7, 9, 11]

target = 7

result = binary_search(sorted_arr, target)

if result != -1:

    print(f"Element found at index {result}")

else:

    print("Element not found")

I find this method to be really powerful for large datasets and prefer it for its algorithmic efficiency and the divide-and-conquer approach.”

5. Write a program in Java to calculate the LCM of a given array of numbers.

Sample Answer

“Calculating the Least Common Multiple (LCM) of multiple numbers involves using the relationship between the Greatest Common Divisor (GCD) and LCM of two numbers. The LCM of two numbers can be found by dividing the product of the numbers by their GCD. I’ll start my process by calculating the LCM of the first two numbers. Then, I’ll use this result to find the LCM with the next number in the array. I’ll continue this iterative process until all numbers in the array are processed, resulting in the LCM of the entire set. Typically, I use the Euclidean algorithm to calculate the GCD where I repeatedly replace the larger number by the remainder when divided by the smaller number until the remainder is zero. 

Here is the final code for it:

import java.util.Scanner;

public class LCMArray {

    public static int gcd(int a, int b) {

        while (b != 0) {

            int temp = b;

            b = a % b;

            a = temp;

        }

        return a;

    }

    public static int lcm(int a, int b) {

        return (a * b) / gcd(a, b);

    }

    public static int lcmOfArray(int[] arr) {

        int result = arr[0];

        for (int i = 1; i < arr.length; i++) {

            result = lcm(result, arr[i]);

        }

        return result;

    }

    public static void main(String[] args) {

        Scanner sc = new Scanner(System.in);

        System.out.print("Enter number of elements: ");

        int n = sc.nextInt();

        int[] numbers = new int[n];

        System.out.println("Enter the numbers:");

        for (int i = 0; i < n; i++) {

HR-Round Wipro Interview Questions and Answers for Freshers

While your coding abilities and problem-solving expertise open the door, the HR interview shapes the final decision by assessing how well you fit into Wipro’s culture and values. As a fresher, this round is often the first real opportunity to showcase your personality, communication skills, and professional mindset. Wipro looks for candidates who demonstrate strong interpersonal skills, adaptability, and a clear sense of career direction.

Let’s quickly explore the most frequently asked HR questions at Wipro for freshers, along with thoughtful, well-structured answers that go beyond generic responses. 

1. Can you tell me something about yourself briefly?

Why Recruiters Ask This Question: This question serves as an icebreaker and provides insight into your communication skills, confidence, and how well you can present your background. It's an opportunity to set the tone for the rest of the interview.

Sample Answer

“I am Krishna, a Computer Science graduate from Dev Bhoomi Institute of Technology with a solid academic record, including a 80% aggregate and top 10% rank in my batch. During my studies, I developed a strong passion for software development, particularly in Java and Python. I completed a capstone project where I designed a web-based inventory management system that improved order processing time by 15% for a local retailer. Besides academics, I interned at Wipro itself, where I contributed to a team developing a customer feedback app, boosting customer engagement by 20%. I am also an active member of the coding club and participated in various hackathons. I pride myself on being a quick learner and a team player. I am eager to bring my technical knowledge, problem-solving skills, and enthusiasm to Wipro. I believe this is the right platform to grow professionally and personally, where I can contribute meaningfully to projects and continue developing my skills in emerging technologies.”

2. Why do you want to work at Wipro?

Why Recruiters Ask This Question: This question assesses your knowledge about the company and your genuine interest in being part of their team. It helps interviewers determine if your values align with Wipro's culture and mission.

Sample Answer

“Wipro’s reputation as a global leader in IT services and consulting excites me because of its continuous innovation in emerging technologies like AI, cloud computing, and automation. The fact that Wipro invested over ₹4,000 crores in digital transformation in the past two years demonstrates its commitment to the future. Additionally, your focus on sustainability and corporate social responsibility aligns with my personal values. I am also impressed by your employee development initiatives – programs like ‘Wipro Elevate’ offer training and mentorship to enhance skills, which is critical for a fresher like me. During my research, I also noted that Wipro was recognized as one of India’s best employers in 2024, reflecting a positive work culture. The company’s global footprint and diverse client base present ample opportunities to work on exciting projects with international exposure. I want to contribute my technical expertise and enthusiasm to such an environment. Working at Wipro would provide me the platform to grow, take on challenging projects, and learn from some of the best minds in the industry.”

3. What’s your #1 strength and your #1 weakness?

Why Recruiters Ask This Question: This question evaluates your self-awareness and honesty. The interviewers want to see if you can critically assess your abilities and areas for improvement, and how you plan to address them.

Sample Answer

“My greatest strength is my adaptability. For instance, during my internship at XYZ Solutions, I was assigned to a project that required knowledge of React, which I hadn’t used before. Within two weeks, I self-studied and contributed 20% of the frontend code, accelerating project delivery by a week. This adaptability helps me stay calm and perform well even in unfamiliar situations. 

On the flip side, my biggest weakness used to be overcommitting. I often took on multiple projects at once, which affected my focus. Realizing this, I started using time-management tools like Trello and Google Calendar, prioritizing tasks based on deadlines and impact. In the last six months, I improved my task completion rate by 30% by limiting my workload and seeking early feedback. I’m learning to balance quality and quantity without compromising either. 

I believe this journey of recognizing and working on my weaknesses makes me a better professional. I’m confident that my adaptability and continuous self-improvement will enable me to contribute effectively to Wipro.”

4. What particular skills do you have for this role?

Why Recruiters Ask This Question: Recruiters want to assess if your skill set aligns with the job requirements and how well you understand the role. This question helps determine your technical and soft skills relevant to the position. 

Sample Answer

“For this role, I believe my strongest skills are programming in Java and Python, database management using SQL, and problem-solving using algorithms. As my final year project, I developed a Java-based student information system that automated data retrieval and reporting, reducing manual effort by 40%. I am comfortable with data structures like trees, graphs, and hash maps, which I applied in coding challenges where I scored in the 90th percentile in a recent online competition. Additionally, I have hands-on experience with SQL queries and database normalization, gained through an internship at XYZ Solutions, where I optimized database performance, reducing query time by 25%.

Beyond technical skills, I have good communication skills, proven by leading a team of five during a college coding contest. I am also proficient in Linux and shell scripting, which adds value when working on server-side applications. I keep myself updated with new technologies by attending webinars and completing courses on platforms like LeetCode and Coursera. I believe these technical and interpersonal skills make me well-suited for this role at Wipro.”

5. Where do you see yourself 5 years down the line?

Why Recruiters Ask This Question: This question helps recruiters understand your career goals and whether they align with the growth opportunities at Wipro. It also indicates your long-term commitment to the company.

Sample Answer

“In five years, I see myself as a seasoned software developer with expertise in emerging technologies such as cloud computing and artificial intelligence. My goal is to contribute to innovative projects that drive business transformation at Wipro. I plan to complete certifications like AWS Solutions Architect and machine learning courses within the next two years to enhance my technical skill set. Additionally, I aim to take on more leadership responsibilities, managing small teams and mentoring junior colleagues, fostering a collaborative environment. 

I am keen to be part of Wipro’s digital transformation initiatives and contribute towards developing scalable, efficient software solutions. Professionally, I want to have a solid portfolio of successfully delivered projects and possibly contribute to open-source communities. Personally, I want to keep growing my problem-solving and project management skills, ensuring that I add value to Wipro’s goals while advancing my career in a dynamic and challenging environment.”

6. Why should we hire you over other candidates?

Why Recruiters Ask This Question: By asking this question, the recruiters want to understand what unique qualities you bring to the table and how you can contribute to the company's success. This is your chance to highlight your strengths and differentiate yourself.

Sample Answer

“You should hire me because I bring a unique combination of strong technical skills, demonstrated problem-solving ability, and a passion for continuous learning. For example, during my internship at XYZ Solutions, I developed a Python script that automated report generation, saving the team 10 hours weekly. My academic record reflects consistent performance with 78% in my major subjects, and I also ranked in the top 15% of my class. 

I also actively participated in hackathons, securing third place in a national competition for building an AI-based chatbot. Beyond technical expertise, I am a team player and have successfully led group projects where I coordinated tasks and resolved conflicts efficiently. My adaptability was proven when I quickly learned new frameworks under tight deadlines, contributing to project success. I’m highly motivated to work at Wipro, and my blend of technical skills, leadership potential, and eagerness to learn makes me a strong fit for this role.”

7. Do you have any questions for me?

Why Recruiters Ask This Question: This question evaluates your genuine interest and engagement with the company and role. It shows whether you have done your research and if you are proactive about clarifying doubts. 

Sample Answer

“Yes, I do have a few questions. 

• First, could you please share more about the typical career progression for freshers joining Wipro in this role?
