To prepare for a Mercor AI interview, build three true examples from your own work before you start, and practise saying each one out loud in about a minute. Then take Mercor’s free practice interview and set up your room, because the official attempt is recorded and reviewed.
A Mercor AI interview is a recorded video conversation with an AI interviewer that asks questions about the role you applied for. Mercor says most interviews take about 20 minutes, and one result can be reused for other roles that need the same interview.
This guide suits you if you have a Mercor application with an interview step and want to prepare your examples. It is not for you if you have not applied yet, because our guide to the Mercor application process covers the earlier steps.
Checked: 18 Oct 2026. AI Trainers FAQ is independent. Platform rules change often, so check Mercor’s own help pages before you start your interview.
TL;DR
- Prepare three true work examples, because the interviewer asks about your real experience.
- Shape each example as situation, decision, check and result, so you stay specific under follow-up questions.
- Take the free practice interview first, because Mercor says it does not affect future opportunities.
- Treat retakes as a backup, because hiring managers can see your retake count.
- Use Chrome on a computer, and test your mic, camera and screen sharing before you begin.
- Write your own answers, because Mercor’s policy bans using AI tools to compose them.

What happens in a Mercor AI interview?
The AI interviewer asks role-specific questions, records your video and audio, and makes a transcript that Mercor uses to judge your fit for the listing. Some interviews go deep into your past work, and others test language or reasoning. Mercor says the AI interview is its only screening method.
Build your Mercor AI interview examples first
Your examples matter more than your setup, because the questions ask what you did and why. Pick three pieces of work that match the role description. Use this four-part shape for each one, because it gives the interviewer something to test.
- Situation: one sentence on the task, the standard you worked to and who relied on it.
- Decision: the choice you made and the reason for it, in plain words.
- Check: how you tested that your work was right, such as a second source, a rule or a calculation.
- Result: what changed, with a number if you have one and can share it.
Example (fictional): A pharmacist applies for a medical review role. Her first example is a dosing question. She checked the guideline, found that kidney function changed the dose, and wrote to the doctor. The dose was changed that day.
The example names a rule, a check and an outcome, so the interviewer can test any part of it.
Keep each example to about one minute when you say it aloud.
Warning: leave out client names, patient details and anything covered by a confidentiality agreement. Describe the type of work and the standard you used instead.
Practise without spending a retake
Mercor offers a practice interview that is free, is not tied to any application, and is not shared with companies. You can take it as many times as you like, so use it to hear your own pace.
Mercor also allows up to three retakes of an official interview. Its waiting room asks you to keep retakes for technical issues, and hiring managers can see your retake count. Only your most recent attempt is reviewed, so a weaker retake replaces a stronger first try.

How should you set up your room and computer?
Use a computer with a working camera and microphone, and test both in the waiting room, because the Start button stays grey until the required checks pass. Mercor recommends the latest Chrome, supports Edge and Safari, and does not support Firefox or mobile browsers.
Run these four checks on the day, because each one fixes a problem Mercor’s help page lists.
- Turn off VPNs and ad blockers, because Mercor says they can block the live session.
- Wear headphones or use an external mic, because Mercor recommends both.
- Keep pen, paper and a calculator nearby, because some interviews need working out.
- Share your entire screen if asked, because Mercor supports full-screen sharing only.
What if the AI interrupts you or the call drops?
Tell the interviewer you were not finished and carry on, because Mercor says you can do that when it interrupts a pause. Long silences can trigger an interruption, so keep talking through your thinking. If the session freezes, reopen the Assessments tab and try again before you use a retake.
If the problem is technical, email Mercor support with a screenshot and the interview name, so the team can see what happened.
Can you use AI tools during the interview?
No. Mercor’s LLM usage policy allows grammar and wording checks, but it bans using large language models to compose your answers, rate model responses, write rationales or evaluate code. Live answer tools break that rule. Mercor also asks you not to share specific interview questions or screenshots online, so keep your preparation notes private.
Our guide to AI trainer interview preparation covers general practice habits, and our AI trainer skills guide explains what evaluation work tests.

Write your first example today
Write your first example on one card today, using the four parts, and say it aloud with a timer. When all three examples run at about a minute each, take Mercor’s free practice interview from your dashboard.
Mercor reuses one interview result across roles that need it, so the time you spend on strong examples now helps every later application that uses the same interview.
