Mock Interview Practice Guide

Overview

This document contains five mock interview sets, each designed to be completed in one hour. Each set consists of either two medium problems or two easy and one medium problem, mirroring a real junior/mid-level technical interview.

How to Use This Guide

1. Time Yourself: Treat each mock session as a real interview. Allocate exactly one hour per session.
2. No Peeking at Solutions: Try to solve each problem without looking up the solution. If you get stuck, take a structured approach:
   • Clarify the problem.
   • Think through brute force approaches.
   • Optimize step by step.
3. Code in a Whiteboard-Style Manner: Avoid running the code immediately. Instead, walk through your logic as if explaining it to an interviewer.
4. Review Your Solutions: After completing the session, compare your approach to an optimal solution.
5. Practice Similar Problems: If a problem was challenging, find and solve 3-5 similar problems to reinforce the concept.

Mock Interview Sets

Each interview covers different topics, ensuring well-rounded preparation. Problems focus on:

• Arrays & Strings
• Recursion & Backtracking
• Stacks, Queues, and Linked Lists
• Binary Search Trees & Greedy Algorithms
• Mixed Concepts

Happy coding and good luck with your interviews!
