    — How it works —

    Three steps to interview confidence.

    Step 01

    Pick your interview

    Behavioral, technical, case, system design — or paste a real job description and we'll build the mock around it.

    Step 02

    Talk it through

    An AI interviewer asks real questions, probes your answers, and follows up just like a hiring manager would.

    Step 03

    Get coached

    A warm, specific scorecard the moment you finish. Where you shone, where to tighten, what to say next time.

    A note from your coach

    • ·

      Loved your situation setup. Crisp and specific.

    • ·

      Add one quantified outcome and this becomes unforgettable.

    • ·

      Slow down before the technical bit. Set context first.

    You're closer than you think. Try one more round.

    — What makes us different —

    Stop studying interviews. Start having them.

    Online courses

    Human coaches

    Insightful but $200+/hr. Hard to schedule. One conversation a week if you're lucky.

    PrepPilot

    Live mocks any time of day, with feedback that actually tells you what to fix. For the price of a coffee.
