Two rounds, one session

The rounds LeetCode skips

A failing test to debug, and a real-world case to design — with an AI interviewer that reacts as you work.

What a session looks like

Bug Fixcheckout total returns NaN
✕ 1 failingcart.test.ts › applies discount

function applyDiscount(price, pct) {
  // pct arrives as "20", not 0.2
  return price - price * pct;
}
