Can Mercor Detect Cheating or AI in Its AI Interview?

Can Mercor detect cheating or AI in its AI interview? What it records, when it needs your whole screen, its AI rules and retakes.

Whether Mercor can detect cheating in its AI interview is a question that produces confident answers from people who have never read Mercor's documentation. Guides around the web describe eye tracking, keystroke logs and thirty-day lockouts, and candidates walk into a twenty-minute conversation with an AI interviewer worried about things Mercor has never said it does.

We wrote this for candidates with a Mercor AI interview ahead who want to know what is recorded, what is checked and what the rules are. It goes through what Mercor's own help center says about the interview setup, the recording, its policy on AI tools and retakes, separates that from the claims it does not make, and then explains what it means if you use an interview copilot such as Verve AI. We make Verve AI, and everything we say about Mercor comes from its published documentation as it stood in October 2026.

Can Mercor detect cheating or AI in its AI interview?

Mercor records the interview on video and audio, keeps an AI-generated transcript, and for some interviews requires you to share your entire screen. Its policy on AI tools states that submissions evidently produced by artificial intelligence will be identified and flagged, and those are the things it documents.

It does not describe how that identification works, and its help center says nothing about tracking tab switches, eye movement or keystrokes during the interview. So the accurate answer to whether Mercor can detect cheating is that it has a full recording and a transcript of everything you say, a view of your whole screen when it asks for one, and a stated intention to flag answers that read as machine-written.

What does Mercor check before the interview starts?

The interview opens in a waiting room that runs a set of checks, and Mercor's AI interview guide explains which of them matter. A working microphone is required for every interview, and screen sharing is required only for interviews that need it, and when it is, Mercor asks you to share your entire screen and not a single window or tab.

The remaining checks, which are that your face is in frame, the lighting is good and the camera is working and steady, are there to produce a clear recording and do not stop you from starting. Mercor also asks that your full face stays visible throughout.

The interview itself runs in a desktop browser. Chrome is recommended, Edge and Safari are supported, and Firefox and mobile browsers are not.

What does Mercor record and keep?

Mercor keeps the video and audio of an official interview along with the transcript, and it uses AI to evaluate the transcript against the role. The questions are generated from your resume and the job description, most interviews take about twenty minutes, and some include a whiteboard that saves automatically.

Three details about that recording are easy to miss. A completed interview is reused across your later applications, so one recording can be seen for many roles. Hiring managers at the companies Mercor works with can see it. And candidates cannot obtain a copy of their own recording or transcript.

Mercor says interview data is not used to train AI models and is not sold.

What are Mercor's rules on using AI?

Mercor publishes an LLM usage policy, and its interview FAQ tells candidates to follow it. The policy allows AI for checking grammar and wording and for small adjustments of tone. It prohibits using AI to compose responses, to write explanations or justifications, and to evaluate code or model outputs.

The same policy warns that responses rewritten entirely by a language model may be readily identified as artificial, and its written assessments sometimes disable copy and paste for the same reason. What Mercor does encourage is ordinary preparation: it suggests having a pen and paper ready, a calculator where relevant, and headphones or an external microphone.

What does Mercor not say it does?

Much of what candidates fear comes from third-party guides and not from Mercor. We could not find any of the following in Mercor's documentation for the AI interview: tracking of tab or window switches, a locked-down browser, checks for a second monitor, eye or gaze tracking, detection of other voices in the room, checks for browser extensions, or a waiting period of thirty days after a failed attempt.

That is a statement about what is documented and not a promise about what happens behind the scenes. It is still useful, because it shows where the real exposure is, which is the recording and the transcript. A person or a model reviewing them will notice an answer read in a flat voice, eyes moving across a line of text, or a response that does not match the experience on your resume.

Identity checks do exist, but as a separate step. Before you are onboarded to a project, Mercor verifies a government ID and a selfie video through a third-party provider, and a background check follows an offer.

What happens if something goes wrong in the interview?

Mercor allows up to three retakes of an interview, counted across every application that uses it, and you start one yourself from the Assessments tab, after which only the most recent attempt is considered. The waiting room asks you to keep retakes for technical problems and notes that hiring managers can see how many you have used, so a retake is not invisible.

An attempt that ends much earlier than planned does not count and has to be retaken, and that retake counts toward the limit. Once the three are used, Mercor's support may grant another for a technical issue, without a guarantee.

Mercor does not publish what happens to an interview that is flagged for AI use. Its conduct policy for people already working on projects describes escalating consequences for undisclosed AI use, ending in suspension from the platform.

Why do audio problems matter so much?

Many interviews that candidates describe as unfair turn out to be audio problems, because the interviewer is a model that only knows what it heard. Mercor's guide notes that the AI may cut in after a long silence or talk over you, and its advice is to keep answers concise, avoid long pauses and ask it to repeat or clarify when you need to.

The setup advice is specific, which is to use Chrome on a laptop or desktop with headphones, close other tabs, and turn off VPNs, ad blockers and privacy extensions, which Mercor lists as causes of an interviewer that does not respond. Since July 2026 Mercor has also blocked sign-ins through VPNs and proxy services altogether.

Mercor offers a practice interview that is free, can be taken as often as you like, is not shared with companies and has no effect on your applications. It is the best place to find audio and camera problems before the attempt that counts.

What does this mean if you use an interview copilot on Mercor?

Whether Mercor can detect cheating matters less than how your answers sound on a recording that many hiring managers may watch, and that is where an interview copilot either helps or hurts.

Verve AI has a Mercor interview mode built for this format. It listens to the AI interviewer, recognizes whether a question is technical, behavioral or competency-based, and suggests a structure for the answer, using your resume and keeping later answers consistent with earlier ones. That last point matters on Mercor, because the questions come from your resume and the interviewer returns to things you have already said. A chat tab called Mercor Solver takes typed questions and screen captures for case or whiteboard problems.

Two practical points follow from Mercor's own documentation. First, Mercor's policy limits AI to grammar and wording and says machine-written answers will be flagged, so suggestions should be treated as prompts for answers you give in your own words, from your own experience. Second, it is worth checking your screen-share setup in advance. Stealth Mode in the Verve AI desktop app is guaranteed to be invisible when you share a window or tab on any platform and when you share your entire screen in the Zoom or Microsoft Teams desktop apps, while Mercor's interview runs in a browser and asks for the entire screen when it needs a share. Mercor's unlimited practice interview lets you see exactly what your setup shows, and our guide to testing interview copilot stealth mode explains how to check.

For many candidates the most valuable use is rehearsal. Verve AI's mock interviews put you in a spoken interview with an AI interviewer and a report afterwards, which is the closest thing to Mercor's format you can practice without spending an attempt. Our Mercor interview copilot page describes the mode in more detail, and you can start on Verve AI's free plan, which includes five mock interviews and three live sessions.
