Code Debrief gives you real problems and asks the questions your interviewer will. Get scored on how well you think, not just whether your code compiles.
function twoSum(nums, target) { // Your interviewer asks: // "What's your approach here?" // "Why not brute force?" // "How would you optimize?" const map = new Map(); for (let i = 0; i <nums.length; i++) { const complement = target - nums[i]; if (map.has(complement)) { return [map.get(complement), i]; } map.set(nums[i], i); }}We've all been there
You've solved 200 Leetcode problems but still blank when asked to explain your approach
The pressure is real
You can copy a solution and make it work — but you couldn't derive it from scratch
The fog sets in
Your system design answers sound vague even to you
Coding problems, system design, debugging scenarios organized by topic and difficulty
No multiple choice. No autocomplete. Just you articulating your approach in plain English
The AI probes your thinking with follow-up questions then scores you on clarity, depth, and understanding
