An AI interviewer that pushes back, runs your code against hidden test cases, and tells you honestly if you would get hired.
Given an array of integers, return indices of the two numbers that add up to a specific target. You may assume each input has exactly one solution.
YOUR APPROACH Brute-force nested loop, rewritten as a single-pass O(n) hash map.
Strong grasp of the hash-map optimization and clear communication throughout the walkthrough.

How it works
Choose the company style, role, topic, and difficulty. Google, Meta, Amazon, whatever you need.
Talk through your approach and write real code while your AI interviewer asks the follow-ups a real one would.
See exactly which hidden test cases passed, how you communicated, and what to fix before the real thing.
A chat-driven interviewer that asks follow-up questions and reacts in real time to your code and reasoning. It's not just a static prompt box.
Your solution runs against real test cases, including hidden ones, in a sandboxed runtime. No guessing whether it actually works.
The problems and the interviewer's tone shift to match whichever company you're prepping for.
Every interview runs on a real countdown, no hints unless you ask, and the pressure of the real thing.
Every session ends with a real breakdown, not just pass or fail: correctness, complexity, approach, and how you communicated.
See your score trend across sessions and know exactly which skill is holding your offer back.
“I built LiveCodePrep because I kept meeting developers who could nail the algorithm but froze the second an interviewer said walk me through your thinking. That's exactly what this fixes: realistic practice, honest feedback, zero fluff.”

Your code runs against real test cases, including hidden ones you can't see, in a sandboxed environment. The AI interviewer also grades how you approached it and communicated, so you get an actual verdict, not just a chat log.
Google, Meta, Amazon, Microsoft, Apple, and general startup-style interviews. The interviewer's tone, pacing, and follow-up style adapt to match your pick.
Nope. Everything runs right in your browser: the code editor, the execution sandbox, and the AI interviewer are all built in.
