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

Interview practice typically requires expensive coaches or awkward role-play with friends. Feedback is subjective and delayed.

II · Build

The craft

AI conducts realistic mock interviews with industry-specific questions. Real-time analysis scores communication clarity, confidence, and answer structure.

III · Proof

What moved after launch

Mock interviews available 24/7 without scheduling. AI feedback identifies weak points in seconds. Personalized coaching adapts to improvement areas.
