A full round, not one question at a time
A real mock interview isn't a single question with a model answer. It's a whole round: it opens with your introduction, asks a few questions, and follows up on what you actually said, pushing for the trade-off you skipped or the metric you left out. It runs out loud, so you practise speaking under pressure rather than typing. And it holds all feedback until the end, because real interviewers don't coach you mid-answer. There's a full walkthrough in how to practise with a mock interview.
Seven rounds, tuned to the job
Pick the round that's next or the one you're weakest on: recruiter screen, hiring-manager round, cross-functional round, leadership panel, executive or VP final, system design, or technical deep-dive. The questions are generated from the specific posting and shaped by your CV, so a Staff Engineer and a Director preparing for the same company get different rounds. System design stays forward-looking, so it tests how you think rather than recapping your CV.
It runs on the real job posting
This is the part most mock-interview tools can't do. You give Calibrd the actual role — paste it into your workspace, or capture it in one click with the Chrome extension on LinkedIn, or paste it from any other careers page — and the mock interview is built from that exact posting, the same way the rest of your interview prep is. You rehearse the job you're applying for, not a generic template pulled from a question bank.
No recordings are kept
Your speech is transcribed so the interviewer can react to it, then the audio is gone: we keep no recordings, and the transcription provider's published policy for that endpoint is zero retention. Your transcripts and debriefs live in your account, encrypted. Never sold, never used to train AI, and you can delete them anytime. There is no cloud library of your recordings sitting somewhere to be breached. After the high-profile leaks of interview transcripts in 2025, that matters. You can read the full privacy approach for the details.
The debrief: would they advance you?
A score on its own doesn't help. When the round ends, you get a verdict (would-advance, borderline, or not-yet), your strengths so you keep doing them, the weak spots each with a concrete fix, the recurring patterns that cost you more than any single answer, a per-question read, and a ranked list of what to drill next. It's graded against the bar for the level you're targeting, which is the part a supportive friend can't give you. Compare the trade-offs in AI vs. a human mock interview.
It doubles as practice for AI interviewers
More first rounds are now run by software (HireVue and other one-way video screens), and they score your transcript and delivery rather than reading the room. Because Calibrd's interviewer is itself an AI that listens and grades structure and clarity, rehearsing here is direct practice for that format.

Mock interview FAQ
What is an AI mock interview?
It's a practice run of a real interview round where an AI plays the interviewer. It asks the questions you're likely to get, listens to your spoken answers, follows up the way a real panel would, and then gives you an honest read on how you did. The point isn't to memorise answers, it's to rehearse the live skill of turning a thought into a clear, structured answer under pressure.
Is Calibrd's mock interview free?
Your first full mock interview is free. After that they come with any paid stretch of time — 5 mocks on a 7-day pass ($9.99), 15 on 30 days ($19.99), 45 on 90 days ($39.99, three months for the price of two). There's no separate subscription just for the mock interview, and nothing to cancel: the time simply runs out.
How does the mock interview work?
You pick a round and the AI interviewer asks each question out loud in a real voice. You answer out loud, and your speech is transcribed (OpenAI Whisper), so it's the same skill as a real interview rather than typing. It follows up on what you actually said, holds all feedback until the end, and then debriefs you on the whole round.
What interview rounds can I practise?
Seven round types: recruiter screen, hiring-manager round, cross-functional round, leadership panel, executive or VP final, system design, and technical deep-dive. The questions are tuned to the specific job, and your CV shapes them (system design stays forward-looking so it tests how you think, not what you've done).
Can I run a mock interview from a real job posting?
Yes, and this is the part most tools can't do. You give Calibrd the actual posting, pasted into your workspace or captured on LinkedIn with the Chrome extension, and the mock interview is generated from that exact role. You're rehearsing the job you're applying for, not a generic template.
Is my interview private? Does my audio get uploaded?
Your speech is transcribed so the interviewer can react to it, then the audio is gone: we keep no recordings, and the transcription provider's published policy for that endpoint is zero retention. Your transcripts and debriefs live in your account, encrypted. Never sold, never used to train AI, and you can delete them anytime. There's no cloud library of your recordings to leak.
What's the best mock interview tool?
It depends on what you need. For free practice with a peer, Pramp pairs you with another candidate. For a session with an experienced human interviewer, services like Prepfully cost more but help for final-stage prep. For unlimited AI practice tuned to the exact job you're applying for, with a graded debrief and no recordings kept, that's where Calibrd fits. Many people use an AI tool for frequent reps and a human for the occasional reality check.
How is this different from Pramp or Exponent?
Pramp and Exponent pair you with a peer over video, which is great for live pressure but depends on someone else being available and being a good interviewer. Calibrd's AI mock runs on demand, any hour, tuned to the exact job you paste, with a debrief graded against the level you're targeting. Many people use both: AI for reps and a graded read, peers for the human unpredictability.
Can it do technical and system design rounds?
Yes. System design and technical deep-dive are two of the seven round types, and they go deeper on follow-ups than the behavioural rounds. System design is kept forward-looking (a design problem, not a recap of your CV), and the technical round digs into your approach and trade-offs the way a real interviewer would.
What feedback do I get?
After the round you get a full debrief: a verdict (would-advance, borderline, or not-yet), your strengths, the weak spots each with a concrete fix, the recurring patterns across your answers (hedging, rambling, trailing off), a per-question read, and a ranked list of what to drill next. It's graded against the bar for the level you're targeting, not flattery.
Can I practise for AI interviews like HireVue?
Yes, that's a natural fit, because the mock interviewer is itself an AI that listens to your spoken answer and scores structure and clarity, exactly like a one-way AI screener. If your first round is run by software, see the guide on how to pass an AI interview, then rehearse it here.
How many mock interviews should I do?
Enough that the format stops being the thing you're fighting, usually two to four rounds. Do one to get over the strangeness of talking to an interviewer, then a few more aimed at the rounds you're weakest on, varying the type each time and using each debrief as the homework for the next run.
