Mock Interview | Low Level Design with Shubham Sachdeva

This session simulates a real Low-Level Design (LLD) interview conducted at product-based companies. You'll be given a design problem and asked to model the system using object-oriented design principles, class relationships, APIs, extensibility considerations, and common design patterns.

During the session, I will evaluate:

• Problem Decomposition: Ability to break down the problem and gather functional requirements, constraints, and edge cases.
• Object-Oriented Design: Understanding and application of core OOP principles.
• Class Design: Identifying appropriate classes, responsibilities, and relationships.
• Design Patterns & Abstractions: Effective use of design patterns and abstractions to solve the problem.
• Extensibility & Maintainability: Ability to design systems that are easy to extend, modify, and maintain.
• API Design: Designing clean interfaces and handling edge cases effectively.
• Communication & Interview Approach: Structured thinking, clarity of explanation, and ability to justify design decisions.

You'll receive detailed feedback on:

• Design quality, architectural decisions, and trade-offs.
• Areas of improvement and common design mistakes or anti-patterns.
• How interviewers evaluate LLD rounds.
• A focused preparation plan based on your performance.

Ideal for: Engineers targeting SDE2, Senior Software Engineer, and Backend Engineer roles at product-based companies.
