- Always answer out loud, even though typing is allowed. The interview is spoken.
- Upload your resume, so the feedback can point to stories you forgot.
- Repeat the same question after reading the rewrite, in your own words. Don't memorise the AI's version.

Try the Mini AppWhat an AI Scorer Cannot Check
- Whether your technical answer holds up. An AI scorer can check that your answer has a structure. It cannot question your design the way an engineer would: “What happens when this queue backs up?”
- Whether you sound senior. Saying “I decided” instead of “we tried”, or naming a trade-off before you are asked, changes how an interviewer reads your level.
- Which English mistakes matter. Some mistakes an interviewer ignores; others change your meaning. A coach who works in tech knows the difference.
- Real pressure. Talking to a person who interrupts you is different from talking to software.
Interviews by AI's own FAQ says its feedback “isn't perfect”. That is honest, and it is true of every AI scorer.
