/ The product

An interviewer that actually talks back.

MockMynd isn't a flashcard app with a chat window. It's a voice agent that runs full mock rounds and grades you like a hiring manager.

Talk, don't type

Speak your answers out loud like a real interview. Our voice AI listens, asks follow-ups, and steers you back on track — just like a senior engineer would.

Trained on real rounds

System design deep dives, DSA under pressure, and behavioral STAR probes. Every prompt is modeled on questions actually asked at top companies.

Feedback that actually helps

Get a per-competency score, transcript with annotations, and a shortlist of exactly what to study next. No generic 'good job'.

Practice on your schedule

45-minute rounds, 15-minute lightning drills, or a full onsite simulator. MockMynd is ready whenever you are, 3am doesn't judge.
