Pick the platform and the kind of role. You get its questions one at a time, in its format, and feedback on each answer the way its interview is scored, then what to fix first.

What the feedback looks for
The scorer works from a transcript of what you said. It looks for depth in your field (the right terms, mechanisms, trade-offs), concrete experience you can own (projects, numbers, outcomes, “I” rather than “we”), reasoning out loud, and answers that lead with the point and then prove it.
Vague claims carry little weight because anyone can make them. An honest “I have not done that; here is how I would approach it” beats a confident guess. The AI interview guide covers setup, integrity checks and retakes for each platform. A message inviting you to an “interview” that asks for money or ID in a chat is a scam: check it here.
Practise the format, not a script: the questions adapt to your resume and your answers, so a memorised answer rarely survives the first follow-up. Pick the platform and the kind of role above, answer each question as you would out loud, and read what the feedback says to change. Mercor also offers its own free practice interview. Our AI interview guide explains how each one is scored.
Mercor's interviewer, Monty, builds its questions from your resume and the job description, and most sessions are Domain Expert interviews about your field and your real work. Most take about 20 minutes on camera. You can retake an interview up to three times across all applications, and a retake replaces your last attempt.
Zara asks open-ended technical questions for the field you select and scenario questions about how you think and communicate; some roles add a coding challenge or a human data exercise. You end each answer yourself with a Continue button and see at the end whether you meet the certification criteria.
It follows each platform's published format, but the questions are written for you by our AI and the real interviewer's questions will differ. The real interviews are spoken and on camera; here you type what you would say, which trains the substance and structure of your answers.
No. Your questions, answers and feedback stay in this browser so you can carry on later, and we keep nothing on our side; each answer is read once by an AI model to give feedback. Our privacy policy says so.
