Can you use AI to answer interview questions?

The split is simple: prepare with AI, then do the interview yourself. The detail behind it is what makes it stick.

The Civil Service Careers candidate guide says you can use AI to prepare, and names what that looks like: mock questions, researching the organisation, getting a feel for industry trends. But it also says do not use AI to create answers for questions you’re asked during a live or pre-recorded interview, or for situation-based questions. The same goes for assessments that evaluate personality and abilities, such as situational judgement and numerical tests. The guide calls it vital that you don’t use AI during any live assessment at any stage. That’s not a word people throw around by accident.

The Civil Service Fast Stream says the same: use generative AI to prepare, not during tests and assessments. It adds that generative AI isn’t always accurate or current. NHSBSA lands in the same place. Avoid using AI to answer interview questions live; use it to generate example questions and do your research.

Then there’s Anthropic, an AI company, where you might expect a relaxed line. Its candidate guidance says live interviews are “all you”, with no AI assistance unless they say otherwise, and take-home assessments are done without AI unless you’re told. Preparing with AI is encouraged. Even the people who build the tools draw the same line.

How to do it well

Start with what the National Careers Service already tells you to do. Read the job description. Research the company. Think about what you’ll be asked. Prepare examples using STAR (situation, task, action, result). Practise with someone you trust, and prepare your own questions too.

AI slots into that list neatly. The Civil Service guide suggests asking it to read the job description and make up mock interview questions, generating sample behaviour questions so you can practise how you deliver your answers, and asking for tips on body language and communication to try out in mock sessions.

Act as an interviewer for this role. Ask me one question at a time from this job description. After each answer, tell me which part of the STAR structure was weak. Don't rewrite my answer.

“Don’t rewrite my answer” is the line that keeps the words yours. You want a sparring partner. The moment you’re reading someone else’s polish back at an interviewer, it tends to show.

Practise out loud, in the room, with your own voice. Typing a perfect answer into a chat window feels productive, but it isn’t the skill you’ll be tested on. And don’t memorise a script. A script falls apart the second a question comes in sideways, whereas a few well-rehearsed examples bend to fit whatever you’re asked.

The National Careers Service also points out that you can ask the interviewer to repeat a question, and you can refer to your notes. The safety net already exists.

Recorded video interviews and online tests deserve a special mention, because people sometimes treat them as a grey area. They count as the assessment. If you’ve been sent a link and a timer, treat AI as off unless the invitation explicitly allows it. If the invitation says nothing, check with the recruiter.

If you use assistive technology, such as captions or transcription because of a disability, ask for it as a reasonable adjustment in advance. Acas explains that under the Equality Act 2010 employers must make reasonable adjustments for disabled job applicants. Declare it and get it agreed before the day.

Rules and risks

The bluntest rules are in medicine. The four-nation Postgraduate National Recruitment Programme Board says AI technologies are not permitted during online interviews for postgraduate training programmes, including medical specialty training. That covers AI-generated responses, virtual assistants, real-time transcription tools and automated scripts. Applicants who need assistive technology must declare it through the reasonable adjustment process.

The consequences are heavier than a polite no. Anyone found using AI may be disqualified and may be referred to the relevant professional or regulatory body. The same statement says assessors may ask you to expand on an answer if they see signs of AI use. A follow-up question is the quickest way to find out whether there’s anything behind a smooth answer, and proper preparation means you’ve got the follow-up covered.

Elsewhere the risks look a little different. The Civil Service may reject applications where AI is used inappropriately. The Fast Stream says that if it suspects AI use during tests and assessments, your application may be withdrawn. Suspected, note.

So the trade is lopsided: a slightly smoother answer on one side; a rejected or withdrawn application, a disqualification, or in medicine a referral to a regulator on the other. Prepare with AI, then close the tab and do the interview as yourself.
