Sample Questions

A taste of your DSA & Coding mock interview.

These are the kinds of scenario-based questions Joshua asks. In a live session they adapt to your answers and your target role.

Find the longest substring without repeating characters. Talk me through your approach and its complexity.

How would you detect a cycle in a linked list, and why does the two-pointer trick work?

Explain how you would decide between BFS and DFS for a given graph problem.

Walk me through a dynamic programming solution to the coin change problem.

Given a rotated sorted array, how do you search it in O(log n)?

How It Works

Three steps to interview-ready.

Pick your level and mode

Choose junior to principal, then text, voice, or full camera + voice simulation for your DSA & Coding interview.

Answer one question at a time

Joshua, your AI interviewer, asks scenario-based questions, pushes for specifics, and adapts to your answers across four phases.

Get scored and see ideal answers

Every answer is rated on accuracy, clarity, depth and confidence, with the ideal response revealed so you improve fast.

FAQ

DSA & Coding mock interview questions, answered.

Is this LeetCode-style practice?

Yes. You get data-structure and algorithm problems and have to reason through approach, edge cases and complexity out loud, exactly as in real coding interviews.

Does it run my code?

It focuses on how you reason about and explain solutions, which is what interviewers grade most. Use it to rehearse your verbal problem-solving and complexity analysis.
