Your AI coding interview coach

Don't just solve it.
Be ready to
explain it.

Practice coding interviews with an AI coach that challenges your thinking, reviews your code, and helps you solve the next problem on your own.

Your approach matters as much as your answer. JavaScript practice.

Arrays · JavaScript

Find the missing pair.

Explain your approach. Then make it work.

Your AI coachBefore you write code, what would you need to remember as you move through the array?

function twoSum(nums, target) {
  const seen = new Map();
  for (let i = 0; i < nums.length; i++) {
    const complement = target - nums[i];
    // What comes next?

Talk through your approach...

Built for the way interviews work

Think it through.
Code it yourself. Get better.

01 / EXPLAIN

Start with your approach.

Talk through the problem, ask questions, and choose a strategy before reaching for the keyboard.

02 / IMPLEMENT

Work with a real challenger.

Your coach asks follow-up questions and offers measured hints, without jumping straight to the solution.

03 / REFLECT

Know what to practice next.

See where your reasoning held up, where your code fell short, and what you can do independently.

A clearer picture of your skills

A passing test isn't the whole story.

Separate a sound idea from a syntax slip. See where your code would break, how well it scales, and how much help you needed.

Illustrative feedback, not a real assessment.
