This service is designed to help both beginners and experienced developers prepare for DSA interviews using a structured, pattern-based approach.

Instead of random problem-solving or memorizing solutions, the focus is on understanding how interviewers evaluate your thinking and how to approach problems step by step.

What we cover

Interview Fundamentals

1. How interviewers evaluate DSA answers
2. How to think out loud during interviews
3. Brute force to optimized solution strategy
4. Common interview failure points

Time & Space Complexity

1. Understanding time and space complexity
2. Analyzing tradeoffs
3. Beginner vs experienced expectations
4. Complexity analysis framework used in interviews

Core DSA Topics (Pattern-Based)

1. Arrays & Strings (sliding window, two pointers, prefix sum, frequency counting)
2. Hashing and hash map patterns
3. Linked lists and pointer-based problems
4. Stacks, queues, and monotonic patterns
5. Trees and tree traversals
6. Heaps and priority queues
7. Graphs (DFS, BFS, shortest path concepts)
8. Recursion and backtracking
9. Dynamic programming (state, transition, optimization)
10. Greedy algorithms and decision-making

Interview Practice

1. Pattern checklist for quick revision
2. Common traps and mistakes to avoid
3. Blind 75 interview problems organized by pattern
4. Hints and approach discussion (no memorization)

This service works well if you:

1. Know DSA concepts but struggle in interviews
2. Get stuck while explaining or optimizing solutions
3. Want clarity on what is expected at different experience levels

The goal is to help you think clearly, structure your approach, and perform confidently in DSA interviews.
