Story arc

How this shipped

Exploring the boundaries of artificial intelligenceThree beats: what pressed against the work, how the stack answered, and what changed once it was live.

I · Constraint

The brief

Technical interview practice is hard to find outside actual interviews. LeetCode solves algorithms but misses the live coding dynamic.

II · Build

The craft

AI interviewer asks follow-up questions based on your approach, evaluates code in real-time, and adjusts difficulty dynamically.

III · Proof

What moved after launch

Live code evaluation catches bugs as you type. Dynamic follow-ups simulate real interviewer behavior. Skill assessment maps strengths and gaps.
