How Mockery works

A short loop that mirrors a real technical round, so the pressure feels familiar on the day.

  1. Choose your stack

    Select a technology and experience level, or upload a resume so questions reflect the work you have actually done.

  2. Answer out loud

    Test your microphone, then speak naturally. Your browser creates a transcript while you answer.

  3. Review the feedback

    See transcript-based analysis of technical accuracy, completeness and the concepts worth revisiting.

Practice in private. Pay only when it helps.

  • Audio is never stored. Only your transcript is analysed.

  • Reports stay private to your account until you delete them.

  • Passes are one-time payments. Nothing renews automatically.

One-time passes

Pay for a practice window, not a subscription.

Your first full interview is free. Buy a pass only when you want a focused stretch of practice.

Compare passes

Hear how your answer sounds before an interviewer does.

The demo needs no account and does not store your answer. No credit card for your first full interview.
