Mock Interview Prompts: 13 AI Drills That Actually Prepare You

13 prompts that put AI in adversarial-interviewer mode — behavioral with follow-up probes, system design with real pushback, take-home review, senior-to-staff calibration, and a scored post-mock report.

The default AI mock interview is useless: you say something vague, the AI says “great answer”, and you walk into the real loop convinced you’re ready. Then a real interviewer probes once and you fold. These prompts force adversarial mode — the model has to push back on capacity estimates, refuse “increase engagement” as a metric, name the failure mode you didn’t mention, and at the end produce a scored rubric you can act on. Pair with the interview debrief prompts so each mock becomes a drill list.

Best for

  • SWE / PM / designer interview prep
  • Career switchers entering unfamiliar interview formats
  • Senior-to-staff IC promotion interviews
  • Internship-to-full-time conversion loops
  • Take-home submission review before sending

1. Behavioral mock with follow-ups

You are a senior {role} hiring manager at {company tier}. Run a 30-minute behavioral mock. Ask me 4 questions one at a time. After each of my answers, push back with 2 follow-up probes. Do not be polite — be rigorously curious. At the end, score me on STAR completeness, signal density, and red flags.

2. System design mock

You are a {company} staff engineer running a 45-minute system design mock. Topic: "{system}". Step 1: ask me to clarify scope (do not give me requirements; make me ask). Step 2: push me on capacity estimation. Step 3: drive me to specify trade-offs in 2 of my choices. End with a scored rubric.

3. PM-product-sense mock

You are a {company} PM interviewer. Ask me a product-sense question: "How would you improve {product}?" Push me on: (a) target user, (b) chosen metric, (c) why this beats alternative features. Don't accept "increase engagement" as a metric.

4. Role-specific deep-tech mock

You are a senior {specialty — e.g., ML platform engineer} interviewer. Run a 30-min mock with 3 questions calibrated to senior level. After each, probe for the failure mode I did not mention. Do not lead. End with a rubric: technical depth, blind spots, communication.

5. Behavioral red-flag-finder mock

Be a skeptical interviewer. I will give you a STAR answer. Find the 3 red flags a real hiring manager would notice (vague metrics, no ownership, no learning, blame-shifting). Be specific about which sentence reveals each flag.

6. Cold-call adversarial mock

Ask me a curveball question I would not prepare for in a {role} interview at {company}. Don't tell me what category it is. After I answer, tell me which interview signal that question tests, and how my answer scored.

7. Role-fit / motivation mock

You are a hiring manager focused on motivation and role-fit. Ask me 5 questions designed to surface whether I actually want this {role} or am applying out of convenience. Then write 100 words on whether you would advance me, and why.

8. Pair-programming mock

You are a senior engineer running a 45-min pair-programming mock. Task: "{task}". Ask me to write code step-by-step. After each chunk, run it mentally and find 1 bug or edge case I missed. End with a hire/no-hire writeup explaining the technical signal you observed.

9. Take-home review mock

I just finished a take-home assignment for {role}. The brief was: {brief}. My submission: {paste}. Pretend you are reviewing it for a real hiring committee. Score on: correctness, code quality, testing, README, scope discipline. List the 3 questions you would ask me in the follow-up.

10. Late-stage hiring-manager round

Play a hiring manager doing the final round before offer. Ask me 4 questions designed to test: strategic thinking, scope-of-ownership, how I handle a failed project, what I will need from them. Push back if I am too rehearsed.

11. Senior-to-staff promotion mock

Run a senior-to-staff IC promotion mock. Ask me 3 scope questions where the right answer requires going wider than my immediate team. Then assess my answers against a staff bar: cross-team influence, strategic decisions, written artifacts. Brutally honest scoring.

12. Reverse-mock: I interview AI

Swap roles. I will interview you. You are applying for {role} at {company}. I ask, you answer. After each round, tell me whether my question was sharp or weak, and what a better question would have been.

13. Post-mock written feedback

Below is the transcript of a mock interview we just did. Write a 300-word post-mock feedback report. Sections: (1) strongest answer + why, (2) weakest answer + what was missing, (3) top 3 patterns I should drill before the real interview, (4) one habit to drop.

Common mistakes

  • Letting AI play “nice interviewer” so every vague answer comes back as “great point”
  • Not requesting follow-up probes — real interviewers push twice, your mock should too
  • No scoring rubric at the end, so the practice gives you no drill list
  • Practicing only behavioral and skipping system design / product sense
  • Using the same mock prompt for every role and company tier
  • Not specifying a level (junior vs senior vs staff) — model defaults to easy
