Using AI During a Job Interview: What's Allowed and What Gets You Cut

Is using AI during a job interview allowed?

The clearest evidence comes from employers that publish candidate AI rules. They agree on the basic split.

Red Hat encourages "using AI tools for interview preparation, research, or mock interviews." Its guidance then says, "Please do not use AI tools or solutions of any kind during business or panel interviews."¹ Some Red Hat teams allow AI tooling in technical interviews, but only if you confirm first and say which tool you will use.

Anthropic takes the same position. It tells candidates to use its assistant to "research Anthropic, practice your answers, and prepare questions for us."² For live interviews, the rule is: "This is all you–no AI assistance unless we indicate otherwise."

Amazon goes further. According to GeekWire's reporting, Amazon's recruiter guidelines say applicants can be disqualified³ if found using an AI tool during interviews. A spokesperson said candidates must acknowledge they won't use unauthorized tools, like GenAI, during the interview.

Many candidates simply don't know the rules. In Greenhouse's 2025 survey, 27% of candidates⁵ said they had never seen an employer policy on AI use in hiring. Silence is not permission, though. Ask.

How many candidates use AI during a job interview?

Resume Genius surveyed 1,000 active US job seekers. As Newsweek reported, 22% of candidates⁴ said they were already using AI during real-time interviews. The same survey found 78% use AI somewhere in their job search.

Preparation is the bigger use. Greenhouse's 2025 Workforce & Hiring Report found that 45% of job seekers⁵ use AI to prepare for interviews. That is the use employers endorse.

Candidates themselves are split on the ethics. Only 19% of US candidates in the same Greenhouse survey said using AI in a live interview crosses the line. Employers set the rules, however, not candidate opinion.

Some vendor data shows the trend rising. Fabric, which sells interview-integrity software, says flagged cheating in its analysis of over 50,000 candidates rose from 15% in June 2025 to 35% by December 2025⁸. Treat that as one vendor's measure, not an industry rate.

Can interviewers tell if you use AI during a job interview?

Greenhouse's November 2025 AI in Hiring report is the best current data. 65% of US hiring managers⁶ said they had caught applicants using AI deceptively. The most common example was reading from AI-generated scripts, cited by 32%.

Employers are also changing the format. In the same report, 39% of hiring managers said they are conducting more in-person interviews to verify authenticity. Google CEO Sundar Pichai has said Google will include at least one round of in-person interviews⁹ for some roles "to make sure the fundamentals are there."

What interviewers notice is mostly behavior, not software:

1. Eyes that track a second screen. Reading looks different from thinking.
2. The same delay before every answer. A copilot needs time to hear the question and respond.
3. Polished but generic answers. Few names, numbers or specific decisions.
4. Weak follow-ups. A prepared answer can't easily explain why you chose option B over option A.

The follow-up problem is the real trap. Interviewers dig into your first answer, and a borrowed answer has no second layer. Our guide to AI video interviews covers how automated formats score answers too.

What are the risks of using AI during a job interview?

Disqualification is the obvious risk, and it is written into some policies. The less obvious risks are often worse.

• Trust damage. Gartner found that 6% of candidates admitted to interview fraud⁷ in a 2025 survey. It also predicts that by 2028, one in four candidate profiles worldwide will be fake. Employers respond by trusting every remote candidate a little less.
• Recording issues. Many live copilots listen to the interviewer's audio. Recording or transcribing a conversation without consent can conflict with employer rules and, in some states, the law.
• Skill gaps after hire. If AI passed the interview, you still have to do the job without it on day one.
• Worse answers. Reading pulls your attention off the person in front of you. Interviews reward conversation, and a script breaks it.

If an interviewer asks whether you used AI on your resume or cover letter, answer honestly. Using AI for written materials is widely accepted when the content is true. Our guide to using AI in job applications covers what to disclose and how.

How should you use AI to prepare for an interview instead?

Every employer policy above encourages AI for preparation. That's where it helps most, because practice is where answers improve.

Here is a five-step prep routine that stays on the right side of the line:

1. Research. Ask AI to summarize the company's products, news and likely challenges. Check each claim against the company's own site.
2. Predict questions. Paste the job description and ask for the ten most likely questions. Our sibling post on ChatGPT interview prep prompts has copy-ready prompts.
3. Draft stories. Turn real projects into STAR method answers. AI structures them; you supply the facts.
4. Mock interview. Run timed practice rounds with an AI mock interview tool, such as the one in Rezoom, and review the feedback.
5. Go tool-free. Do your last two practice rounds with no AI and no notes.

Before you start prep, make sure the resume the interviewer reads matches the stories you will tell. Run it through the free Rezoom ATS resume checker against the job description, so the skills you plan to discuss are actually on the page.

What about AI-run interviews and one-way video?

AI on the employer's side is now common. Greenhouse's November 2025 report found that 54% of US job seekers have encountered an AI-led interview. That does not make candidate-side AI acceptable.

For these formats, preparation matters even more because there is no human to build rapport with. See our guides to one-way video interview tips, HireVue interview tips and the AI recruiter phone interview.

The bottom line on AI during a job interview is simple. Use it hard before the call, put it away during the call, and ask first whenever a round might be the exception.
