A mock interview is a practice run of a job interview: someone - or an AI - plays the interviewer, asks the questions you are likely to face, and gives you feedback so you walk into the real thing prepared. It is the single most effective way to turn interview anxiety into a routine you have already rehearsed.
Quick answer: A mock interview simulates a real interview so you can practice answering out loud and get feedback before it counts. You can do one with a peer, a career coach, or an AI mock interview that calls you and grades your answers. The most useful mock interviews are spoken, mirror the exact role you are targeting, and end with specific, honest feedback you can act on.
What is a mock interview?
A mock interview recreates the format and pressure of a real interview without the stakes. You answer realistic questions for your target role, out loud, in a back-and-forth conversation, then review what worked and what did not. The point is not to memorize answers; it is to rehearse thinking and speaking under pressure so the real interview feels familiar.
Good mock interviews share three traits: they are spoken rather than typed, they are tailored to the specific job, and they produce feedback. Miss any one of those and you are just reading notes.
Why do mock interviews work?
Interviewing is a performance skill, and performance skills improve with reps, not with reading. Three things make mock interviews effective:
- You practice out loud. Rehearsing silently hides the rambling, filler words, and answers that trail off without a result. You only catch those when you hear yourself say them.
- You get feedback. A neutral grader tells you which answers landed and which did not, so your next rep is better instead of just longer.
- You lower your nerves. Most interview anxiety comes from novelty. After a few realistic run-throughs, the real conversation stops feeling like a first attempt.
What types of mock interviews are there?
There are three common ways to run a mock interview, and they trade off realism, feedback quality, cost, and how easily you can actually book one.
| Type | Feedback quality | Cost | Availability |
|---|---|---|---|
| Friend or peer | Uneven, usually too kind | Free | Depends on schedules |
| Career coach | High | High per session | Slow to book |
| AI mock interview | High and instant | Low, often a free tier | On demand, 24/7 |
A friend is free but usually too easy on you and rarely knows your field. A career coach gives excellent feedback but costs a lot and is slow to schedule. An AI mock interview sits in the sweet spot: coach-style feedback, available on demand, at a fraction of the cost.
What is an AI mock interview (AI practice interview)?
An AI mock interview is a practice interview run by an AI that plays the interviewer, asks questions tailored to your target role, and grades your answers afterward. Instead of scheduling a person, you start a session whenever you want, including at 10pm the night before.
With Nova Interviewer it works by phone: you paste the job description, the AI calls you, runs a realistic interview for that exact role, follows up when an answer is vague, then scores you with specific coaching notes on what to fix. Because it reacts to what you actually say, an AI practice interview feels far closer to the real thing than reading a question list. People also search for this as an "AI practice interview" or "interview practice AI" - it is the same idea.
How do you do a mock interview?
- Pick the role and pull the top skills from the job description.
- Prepare a few flexible stories using the STAR method, drawn from the common behavioral interview questions.
- Run a full session out loud without stopping - treat it like the real call.
- Review the feedback and note one or two things to fix.
- Run it again. Most of the improvement comes from the second and third rep.

What questions will you get in a mock interview?
A good mock interview pulls from the same predictable buckets as a real one: an opening question like "tell me about yourself", behavioral questions, role-specific questions, and situational hypotheticals. For a ready-made set to rehearse, work through our list of mock interview questions.
How do you get feedback that actually improves you?
Feedback is the ingredient most practice skips. "You did great" from a friend does not tell you what to change. Useful feedback is specific and tied to individual answers: this story was strong, this answer buried the result, this one ran ninety seconds too long. Then you fix one thing at a time and re-run. An AI mock interview gives you this automatically, a grade plus concrete notes, so every rep compounds.
How to run your first mock interview
You do not need to prepare for weeks. Pick the role, paste the job description, and start a mock interview that calls your phone and grades you. Your first free session shows you exactly where you stand. If you want to prepare without paying, here are the best free interview practice options.
Bottom line: A mock interview is the highest-leverage thing you can do before an interview. It makes you practice out loud, gives you honest feedback, and turns nerves into rehearsed routine. Do at least one realistic, spoken run-through for your target role, and ideally two or three, before the real conversation.
