Built for the interview. Not for chat.

A general AI waits for your prompt and agrees with you. This one asks, pushes back, and shows you exactly what to fix.

It asks. You answer.

What changes when the AI runs the interview.

Hear it fixed as you speak.

The coach counts what weakens an answer and what lands with this job.
You said
Um, I guess there was this one launch where we, like, kind of had to ship the checkout redesign fast, and honestly I think I was sort of the one who pushed to skip the performance budget.
Coach's version
I owned the call: we shipped without the performance budget, and p75 LCP went from 1.9 to 3.4 seconds.

What did skipping it cost you?
p75 LCP went from 1.9 to 3.4 seconds in the first week. We rolled back behind a flag and re-shipped it server-rendered.

Different people. Different pressure.

Each interviewer has their own personality and difficulty, so you learn to handle the easy‑going manager and the tough one before either is real.
