The short answer: AI chat assistants such as ChatGPT, Claude and Gemini are good at generating likely questions from a job posting, playing the interviewer with follow-ups, helping you shape real stories into the STAR format, and critiquing your answers. They’re bad at knowing your experience, so never let them invent stories, and typed answers are not the same as speaking under pressure. Use the 20 prompts below, replace the parts in [brackets], and always finish by answering out loud. Employers draw a clear line: McKinsey, for example, calls using AI to practice interview questions “encouraged” but generating real-time answers during an interview “not allowed.”
Rules for practicing with AI
- Use your own stories. AI can structure and tighten them; it must not make them up. Interviewers ask follow-ups that expose invented details.
- Give it context: the job posting, your resume, the company.
- Ask for one question at a time, and answer before seeing the next.
- Ask for honest, specific feedback, not praise.
- Say your answers out loud. Type them after you’ve said them, or use voice mode.
- Don’t use AI during a real interview or assessment unless the employer explicitly allows it.
- Don’t paste confidential information from your current employer.
Prompts to generate questions
1. Questions from a job posting
Here is a job posting: [paste]. List the 12 interview questions I’m most likely to be asked for this role, grouped into behavioral, role-specific and motivation questions. For each, say which requirement in the posting it tests.
2. Company-specific questions
I’m interviewing for [role] at [company]. Based on this company’s published values [paste them], write 8 behavioral questions an interviewer might ask to test each value.
3. Hard follow-ups
For the question “[question]”, list the five toughest follow-up questions an experienced interviewer might ask after a good first answer.

5. A full mock interview
Act as a hiring manager interviewing me for [role] at [type of company]. Ask me one question at a time, starting with “Tell me about yourself”. Wait for my answer before asking the next. Ask a follow-up when my answer is vague. After eight questions, give me feedback.
6. A tough interviewer
Act as a skeptical interviewer. After each of my answers, push back once with a pointed follow-up, as a real interviewer would if the answer lacked evidence or clarity.
7. A behavioral round for one competency
Interview me on [leadership / conflict / teamwork / problem solving] only. Ask three “tell me about a time” questions, one at a time, with follow-ups.
8. A panel
Simulate a panel of three interviewers for [role]: a hiring manager, a peer and an HR partner. Each asks one question in turn, in their own style.
Prompts to build STAR stories
9. Turn notes into a STAR outline
Here are rough notes about something I did at work: [notes]. Organize them into Situation, Task, Action, Result. Don’t add any facts I didn’t give you; instead, list the details I should add, such as numbers or what I personally did.
10. Find the result
Here’s a story I plan to tell: [story]. The result is weak. Ask me questions that would help me find a measurable result or impact I haven’t mentioned.
11. Map stories to questions
Here are my five best stories: [short summaries]. Map each to the common behavioral questions it could answer, and tell me which common questions I don’t have a story for yet.
12. Shorten an answer
This answer takes about three minutes to say: [answer]. Help me cut it to about 90 seconds while keeping the most important actions and the result. Keep my wording where possible.
Prompts for feedback
13. Honest critique
Here is my answer to “[question]”: [answer]. Critique it honestly as an interviewer. Score it from 1 to 5 on relevance, structure, specificity and impact, and tell me the single most important thing to fix.
14. Check the question was answered
Did this answer actually answer the question “[question]”? Point to where it drifts: [answer].
15. Find vague claims
List every vague claim in this answer that an interviewer would want evidence for: [answer].
16. “I” vs “we”
In this answer, highlight where I describe what the team did instead of what I did: [answer].
Prompts for specific situations
17. Weakness question
Help me answer “What is your greatest weakness?” using this real weakness: [weakness] and what I’m doing about it: [actions]. Avoid clichés like perfectionism.
18. Explaining a gap or a layoff
Help me explain [a six-month gap / being laid off] in two or three honest, positive sentences, and suggest how to move the conversation forward.
19. Questions to ask the interviewer
Based on this job posting [paste], suggest 8 thoughtful questions I could ask the interviewer, and say which to ask a recruiter, a hiring manager and a senior leader.
20. Salary
I’m interviewing for [role] in [city]. How should I answer “What are your salary expectations?” if my researched range is [range]? Give me two versions: one that gives a range and one that asks for theirs first.
Where AI practice falls short
- It can’t hear you. Typing a polished answer is not the same as saying it clearly under pressure.
- It can be too kind. Ask explicitly for criticism.
- It can make things up, including facts about companies. Check anything factual.
That’s the gap Huru fills: you answer out loud on camera, and every answer is scored out of 100 on relevance, structure, specificity, impact and articulation, with the one thing to fix. See also our guides to the STAR method, common interview questions and the best AI mock interview tools.
