A new kind of software has appeared around video interviews: tools that listen to the conversation while it happens and put suggested answers on the candidate's screen. They are often called interview overlays or live AI interview assistants.
This article explains what they are, why people are tempted by them, what employers are doing in response and what the risks are for you. It is information, not a recommendation: we don't name products, and we won't explain how to use or hide one. At the end, you'll find the honest alternative.
What an interview overlay tool is
An interview overlay is software that runs on the candidate's computer or phone during a live interview. It captures the audio of the call, turns the interviewer's questions into text, sends them to an AI model and displays a suggested answer on screen, usually within seconds, so the candidate can read it or paraphrase it while answering.
That makes it different from three things that can look similar:
- Preparation tools. Using AI before the interview to research the company or practise questions is a different matter, and most employers expect it. We cover that line in using AI in a job interview.
- Tools the employer runs. Some employers record or transcribe interviews themselves, or use AI to assess candidates. That happens with the employer's knowledge and comes with its own rules.
- Assistive technology agreed in advance. If you have a disability, you can ask for adjustments to how the interview runs. That's arranged openly with the employer, not done in secret.
What defines an overlay is the combination: live, during the interview, and without the interviewer knowing.
Why candidates are tempted
The temptation is easy to understand. Hiring processes have become long, with screening calls, video interviews, assessments and several rounds, and each one can end the process. Interviews on video make it feel as if no one would notice a second window. And for anyone who freezes under pressure, the promise of always having an answer ready is powerful.
If nerves are the real problem, there are better fixes than a script in your ear: rehearsal, mock interviews and, where you have a disability, adjustments you're entitled to ask for. Our guide to interview anxiety covers them.
What employers do about it
Employers can't see your screen, but they don't have to. These are the responses that have become common:
- More in-person or on-site rounds, especially at the final stage, where there is no second screen to rely on.
- Follow-up questions that probe. “Why did you choose that approach?”, “What would you do differently?”, “Walk me through the numbers.” A prepared or generated answer holds up for one question; it rarely survives three follow-ups about your own work.
- Screen sharing or camera rules for remote interviews and technical exercises.
- Written rules on AI use that candidates are asked to read, and sometimes to accept, before the interview.
Some employers publish these rules on their own sites. Anthropic's guidance for candidates encourages using its AI to research the company and practise answers, but for live interviews says no AI assistance unless the company indicates otherwise (Anthropic). Greenhouse, which makes hiring software, tells its own candidates not to use AI to supplement their performance in a live interview unless instructed or agreed in advance, and says undisclosed AI use outside its guidelines may lead to disqualification (Greenhouse).
Remote interviews also raised a separate problem: identity. In June 2022 the FBI's Internet Crime Complaint Center warned of complaints about people using deepfakes and stolen personal information to apply for remote IT, programming, database and software jobs; in some video interviews, the applicant's lip movements didn't match the audio (FBI IC3). That's a different issue from answer overlays, but it explains why many employers now check identity carefully in remote hiring and add a face-to-face step.
The risks for you
Your offer. If an employer's rules forbid AI during interviews and the use comes to light, the simplest outcome is that you are out of the process; Greenhouse's guidelines say exactly that. If it comes to light after you have started, the employer may see the whole hiring decision as based on a misrepresentation, which puts the job itself at risk.
The mismatch. You get hired for the person you presented. If a tool supplied the answers, you start the job needing to perform at the level it described, from the first week, in meetings where there is no overlay. That's a hard place to begin a job, and often a probation period.
A worse interview. Reading suggestions while listening splits your attention. Answers come out generic, you lose the thread of follow-up questions, and the conversation, which is what interviewers judge most, gets weaker.
Other people's data. An overlay captures what the interviewer says, in their voice, and sends it to a third-party service. Under the UK GDPR and the EU GDPR, personal data is any information relating to an identified or identifiable person (ICO, GDPR art. 4). The interviewer hasn't agreed to their words being recorded and processed by a company they don't know, and interviews often include confidential details about the team or the business. Whether a particular use breaks a particular law depends on where you are and how the tool works, and this isn't legal advice; but it is a real issue, not a technicality.
Your own data. The same service receives your voice, your answers and often your resume. Check what any tool keeps and for how long before you give it anything.
The honest alternative
Everything an overlay promises can be built before the interview, honestly.
Prepare the answers you'll need. Most questions are predictable: “tell me about yourself”, why this role, your strengths, and “tell me about a time when…” questions. Prepare three or four real stories with the STAR method, as in our job interview preparation guide, and rehearse them out loud.
Practise under pressure. Mock interviews with a friend or a careers adviser train exactly what overlays try to replace: answering a question you didn't expect. Jobra's interview simulator, on the Pro and Max plans, asks eight questions for the role and gives you feedback after each typed answer, with a STAR breakdown, a tip and a score out of 10. It's practice before the interview, not help during it.
Be open about the AI you used before. Using AI to research a company, prepare questions or polish your resume is common and, for many employers, expected. If someone asks, say what you used it for. And if you need support during the interview because of a disability, ask for an adjustment in advance.
Frequently asked questions
What is an AI interview overlay?
Software that listens to a live interview, turns the interviewer's questions into text and shows suggested answers on the candidate's screen while the interview is going on, without the interviewer knowing.
Is it allowed to use an AI assistant during an interview?
Only if the employer says so. Some employers publish rules: Anthropic and Greenhouse, for example, both say no AI assistance in live interviews unless they indicate or agree otherwise. If there's no rule, ask the recruiter before the interview, not after.
Can an employer tell if I'm using one?
Employers don't need to detect the software to see the problem. Follow-up questions, in-person rounds and, in the end, the job itself show whether you can do what you described.
Is it a privacy problem to record the interviewer?
It can be. What the interviewer says, in their voice, is information about an identifiable person, which is personal data under the UK and EU GDPR. Sending it to a third-party service without their knowledge raises real data protection questions.
Can I use AI to prepare for an interview?
Yes. Researching the company, practising likely questions and polishing your stories with AI is common and widely accepted. Just make sure every example you give is true and your own.
