ChatGPT mock interview the prompts that work, step by step

How to do a mock interview with ChatGPT

To run a ChatGPT mock interview: paste the job description and your resume, tell it to act as the interviewer for that role, ask it to ask one question at a time and wait for your answer, and ask for short feedback after each answer. Use voice mode if you can, so you practice speaking, not typing. Then finish with a practice session with a real person.

This guide gives you copy-and-paste prompts for each step, what ChatGPT does well and badly as an interviewer, and the privacy and accuracy cautions MIT's career office recommends.

Before you start

• Have the job description ready. The more specific the posting, the better the questions.
• Prepare a cleaned-up resume. Remove your phone number, address and anything you would not want stored.
• Pick voice or text. Voice mode is closer to a real interview. Text is useful for drafting STAR stories first.
• Set a time. A real first interview is often around 30 minutes; plan a session of that length.

Prompts for a ChatGPT mock interview

1. Predict the questions

Here is a job description and my resume. Based on them, list the 5 core competencies this employer is most likely to test, and for each one, tell me which experience on my resume best shows it.

This follows MIT CAPD's suggestion: ask AI to predict the core competencies you will be asked about and which of your experiences address them.

2. Narrow it down

From those competencies, write the 8 questions a hiring manager would realistically ask in a 30-minute first interview for this role. Mix behavioral, situational and "about you" questions.

Asking for a realistic 30-minute set stops it from producing 50 generic questions.

3. Start the mock interview

Now act as the hiring manager for this role. Ask me the questions one at a time. Wait for my answer before asking the next one. Do not give feedback until I say "feedback". Stay in character and ask one follow-up question when my answer is vague.

The "wait for my answer" line is the most important; without it, ChatGPT tends to ask everything at once.

4. Ask for feedback

Feedback: for my last answer, tell me in 4 short bullets (1) did I answer the question in my first sentence, (2) did I use a specific example with a result, (3) what was missing, (4) one sentence I could say instead. Be direct.

Short, structured feedback is easier to act on than a long paragraph.

5. Turn up the difficulty

Ask me the hardest follow-up question a skeptical interviewer would ask about my last answer.

Real interviewers probe. This prepares you for "What would you do differently?" and "What was your part, exactly?".

6. Wrap up

End the interview. Give me a summary: my strongest answer, my weakest answer, the 3 things to fix before the real interview, and 2 questions I should ask the interviewer.

Save this summary; it is your to-do list.

Getting useful feedback from ChatGPT

• Ask for a rubric, not praise. Chat assistants tend to be kind. "Score this from 1 to 5 on structure, evidence and relevance, and explain any score under 4" gets better feedback.
• Push back on poor questions. MIT CAPD advises not to accept AI's questions blindly: if they do not fit the role, ask it to refocus.
• Answer out loud even in text mode. Say the answer, then type a short version. Speaking is the skill you are training.
• Repeat the weak ones. Ask the same question again and answer it with the fix.

What a ChatGPT mock interview cannot do

• Judge your delivery. MIT CAPD notes AI cannot help with delivery the way a person can: eye contact, posture, tone.
• Know the company's real process. Its information can be out of date, and it does not know what this employer actually asks.
• Measure your speaking. In plain chat it does not count your filler words or time your answers. Our free AI mock interview does: it reads questions aloud, asks follow-ups and reports pace, filler words, pauses, STAR structure and content.
• Help in the live interview. A chat window cannot hear the interviewer. Typing questions during a real call is slow and obvious; see ClapAssist vs ChatGPT for how a live copilot differs.

Privacy and accuracy cautions

MIT's career office gives three cautions worth following:

• Personal data: "Be considerate of what personal data you are uploading." Use a temporary chat if your assistant offers one, and remove contact details from your resume first.
• Accuracy: "AI might have found information that is outdated." Check any fact about the company yourself before you mention it in an interview.
• No scripts: memorizing AI-written answers word for word is, in MIT's words, "the biggest trap". Use AI to find your examples and structure; say them in your own words.

And its main advice: "Pair any AI-assisted interview prep with a real-life mock interview."

Other ways to practice

• ClapAssist AI mock interview: free, no account, spoken practice with a report (questions read in English).
• Interview simulator: a full eight-question practice interview with a clock.
• Google Interview Warmup alternatives, including Gemini Live.
• Big Interview: a paid course, sometimes free through schools.
