ChatGPT Interview Prep: Mock Interview Prompts and STAR Answers

What ChatGPT can do for your interview prep

ChatGPT, Claude and Gemini can act as a patient practice partner. They can predict likely questions from the job posting, help you turn your experience into clear stories, play the interviewer, and give you feedback on how long, vague or convincing your answers are.

They can't know what this specific interviewer will ask, and they don't know your career beyond what you tell them. Treat their questions as likely, not certain, and their model answers as raw material to rework in your own voice, not scripts to memorise.

What to give it before you start

• The job title, the company and the full job posting.
• Your resume (or CV) or a summary of your most relevant experience.
• The interview format: a recruiter phone screen, a call with the hiring manager, a technical round, a panel, a case exercise or a recorded video.
• A few real situations you remember: a project, a conflict, a mistake, an achievement. Rough notes are enough.
• What worries you being asked: a gap, a missing skill, a career change, being let go.
• How many days you have left, so the practice plan is realistic.

Build STAR answers from your real experience

Behavioural questions ('Tell me about a time when…') are easier with the STAR method: Situation, Task, Action, Result. It keeps your answer focused on what you did and how it turned out, instead of drifting.

Help me turn this real experience into an interview answer using the STAR method (Situation, Task, Action, Result).
Role I'm interviewing for: [job title]
Question it should answer: [e.g. 'Tell me about a time you handled a difficult stakeholder']
What happened, in my own rough words:
[describe the situation]

Keep it to about 60–90 seconds when spoken. Focus on what I did, not what the team did. Use only the facts I've given you: if the result is unclear or a detail is missing, write [to complete] and ask me about it. Then tell me which other common questions this same story could answer.

Act as a hiring manager for the role below. Based on the job posting and my resume, list the [10] questions I'm most likely to be asked, grouped into: role-specific/technical, behavioural, motivation and fit, and situational ('What would you do if…').
For each one, explain in one line what the interviewer is really checking, and outline an answer using only my real experience. Mark anything you'd need from me as [to complete].

Job posting:
[paste the posting]

My resume:
[paste your resume]

Mock interview prompt: practise with ChatGPT

The most useful exercise is a realistic practice interview, one question at a time. Type your answers, or use the voice mode if your assistant has one, so you also practise saying them out loud.

Act as the interviewer for the [job title] role at [company or type of company]. This is a [recruiter screen / hiring manager interview / technical interview].
Job posting: [paste it or summarise it]
My background: [short summary or paste your resume]

Rules:
- Ask me one question at a time and wait for my answer.
- After each answer, give me brief feedback: what worked, what was vague or too long, and a stronger way to phrase it using only what I said.
- Mix behavioural, role-specific and motivation questions, and include at least one follow-up that digs into a weak spot.
- After [8] questions, give me an overall summary with my three strongest answers and the three to practise again.
Start with the first question.

Repeat the mock interview a day later with the instruction 'ask me different questions from last time' and compare how your answers have improved.

Tough questions, salary talk and questions to ask

Most nerves come from a handful of questions: gaps in your resume, why you're leaving, your weaknesses, salary expectations. Prepare a short, honest answer for each, plus two or three good questions to ask at the end.

I have an interview for [job title] at [company]. These are the topics I'm worried about being asked: [e.g. a 10-month gap, a career change, little experience with X].
1. For each topic, give me the likely question and a short, honest way to answer it (30–45 seconds), without hiding anything or making excuses.
2. Give me five thoughtful questions to ask the interviewer about the role, the team and how success is measured, avoiding anything I could easily find on their website.

If pay is likely to come up, prepare that conversation separately using your own research on pay for the role and location. AI doesn't know real salary data for your role, so don't rely on it for figures.

What not to do

• Using AI during the real interview, whether it's live, on video or recorded. Prepare beforehand, then answer on your own.
• Memorising scripts word for word. It sounds rehearsed and falls apart with the first follow-up question.
• Inventing stories or results. Interviewers dig into details, and anything you claim may be checked.
• Treating the AI's list as the questions you will definitely get. It's practice, not a prediction.
• Trusting what the AI says about the company without checking the company's own website and official sources.

Questions about what you can legally be asked in an interview depend on the country. For that, check your government's official employment guidance rather than an AI answer.

Do it with a template

PromptYa's interview prep template asks for the role, the company, the posting, your experience, the level, the interview format, the question types you want to practise, your stories and what worries you, and turns it all into a complete prompt. The AI returns what they're really looking for, your 'tell me about yourself' introduction, a STAR story bank, likely questions with model answers, how to handle the uncomfortable ones, questions to ask the interviewer and a practice plan.

You can copy the prompt, open it in ChatGPT or Claude already filled in, or copy it and open Gemini.
