How to prepare for the Mercor AI interview

Free interview prep

Most Mercor roles start with a video interview run by an AI interviewer. Here is how it works, taken from Mercor's own help pages, plus practice questions we wrote.

This page explains how the interview works. It does not mean you will pass or get an offer. Mercor decides who it hires.

How the interview works

  1. Upload your CV and answer the role's written or multiple-choice questions.
  2. Do the AI interview. Most take about 20 minutes, in English unless the role says otherwise.
  3. Some interviews ask detailed questions about your past work. Others test your language or reasoning.
  4. Some roles add a skills test. Most tests allow only one submission.
  5. You only do each interview once. It counts for every role that uses it.
  6. You can retake an official interview up to 3 times in total. Hiring teams see the retake count, and a retake resets your application.
  7. Before a project starts, you verify your ID. Some roles also have a paid work trial of about 4 to 6 hours.

What to set up

  • A computer with a working camera and microphone. Some interviews do not work on a phone.
  • Chrome is the browser Mercor suggests. Firefox is not supported.
  • A quiet room and a stable internet connection. Headphones help.
  • Some interviews ask you to share your whole screen.
  • Pen and paper, and a calculator if the role needs one.

The rules

  • Do not use AI tools to write your answers. Mercor says it flags answers that are clearly written by AI.
  • In tests, do not copy from other sources or get help from other people.
  • Do not share the interview questions or screenshots.

Before you start

  • Take Mercor's free practice interview first. It is not tied to any application, and you can repeat it.
  • Pick a time when you are rested. Make sure your face is visible and your voice is clear.
  • Do not go silent for long. If you need a moment, say so. You can ask the AI to repeat a question.
  • If the AI goes to the next question too early, tell it you were not finished.
  • Give your best answer on the first try. A retake shows on your application.

Practice questions

Mercor does not publish its questions. We wrote these from the kinds of questions Mercor describes. Answer each one out loud in 1 to 2 minutes.

Your past work

  1. Describe a project you are proud of. What was your part, and what was hard?
  2. Tell me about a mistake you made at work. How did you find it, and what did you change?
  3. Which tool or method do you use most in your field? Explain it to someone new to it.

Reasoning

  1. Two answers to the same question both look correct. How do you decide which one is better?
  2. You get an instruction that can be read two ways. What do you do before you start?

Language roles

  1. Explain a common idiom in your language to someone who does not speak it.
  2. Read a short sentence aloud in your language, then translate it into English.
