To run a mock interview on your own, pick a real job ad, choose six questions you'd expect for it, and answer them out loud in one go while recording yourself. Don't stop to restart. Then watch it back with a checklist and redo your weakest answer. The whole thing takes 30 minutes and costs nothing. It catches problems that reading your notes never will: rambling, filler words, and the story you thought you knew but can't actually tell in under two minutes.
Below: a minute-by-minute plan, which six questions to choose, how to set up, what to look for when you watch it back, and how to make solo practice feel like the real thing.
Why practising out loud beats practising in your head
In your head, every answer is fluent. You skip the boring bits, your examples have tidy endings, and you never say "um". Out loud, you find out that your best story takes four minutes to tell, that you start three answers with "So, basically", and that you can't remember the number that made the example impressive.
A mock interview moves those discoveries from the interview to your kitchen table, where they're free.
The 30-minute mock interview plan
| Minutes | What you do |
|---|---|
| 0–5 | Choose the job ad and your six questions. Set up your phone or laptop to record. |
| 5–20 | Run the interview: six questions, answered out loud, no restarts. |
| 20–28 | Watch the recording back with the checklist below. Note one thing to keep and one to fix. |
| 28–30 | Redo your weakest answer, once, straight away. |
That's it. Thirty minutes, once or twice before each interview, is worth more than an evening of reading "top interview tips".
Step 1: Choose the job and your six questions
Use a real job ad, ideally the one you're interviewing for. Questions only feel real when they're about a real job.
Then pick one question from each of these six types:
- The opener. "Tell me about yourself." Almost every interview starts here, and it sets the tone. (How to answer "tell me about yourself".)
- Motivation. "Why do you want this job?" or "Why should we hire you?" (Example answers that aren't buzzwords.)
- A behavioural question. "Tell me about a time you…", matched to a skill in the job ad. (30 behavioural questions with STAR answers.)
- A second behavioural question. Pick a different skill, preferably one you feel less sure about.
- A role-specific question. Something only someone in this job would be asked. For a support role, for example, "How would you handle a customer who wants a refund we can't give?" (Customer service interview questions shows what these look like.)
- The curveball. "What's your greatest weakness?" or "Where do you see yourself in five years?" Something you'd rather not be asked.
Finish with the question every interview ends on: "Do you have any questions for us?" Have two ready. (Questions to ask at the end of an interview.)
Not sure what your profession gets asked? Provitude's practice sessions have question sets for dozens of professions, from customer support and sales to software engineering and teaching.
Step 2: Set the scene
- Record yourself. A phone propped at eye level is fine. Frame yourself like a video call: head and shoulders, light in front of you, not behind.
- Have the questions read to you, or put them where you'd look at an interviewer. Reading questions off your own notes trains you to look down. In supported browsers, Provitude's practice mode can read each question aloud.
- Put your notes away. You won't have them in the room. On a video interview you might, but people can tell when you're reading.
- Dress the part, at least from the waist up. It sounds silly. It also changes how you sit and speak.
- Use the time of day of the real interview if you can. A 9 a.m. interview needs a 9 a.m. voice.
Step 3: Run it without stopping
Three rules make the difference between a mock interview and a rehearsal:
- No restarts. If you stumble, recover and carry on, exactly as you would in the room. Recovering well is a skill you can practise.
- Pauses are allowed. Three seconds of silence to think feels endless to you and perfectly normal to an interviewer. Practise taking them.
- Watch the clock. Most answers should take 1–2 minutes. Openers and "why should we hire you" answers can be shorter, around a minute. If an answer passes three minutes, it's two answers.
Provitude's mock mode is built for this: it hides the hints, keeps you moving through the questions, and shows a timer while you answer. In browsers that support it, you can speak your answer and see it typed out as you go, which makes the review much quicker.
Step 4: Watch it back with this checklist
Watch the recording once all the way through. Then watch one or two answers again with the sound off. It's the fastest way to notice what your face and hands are doing.
| Check | What good looks like |
|---|---|
| First sentence answers the question | You don't spend 30 seconds warming up. |
| A specific example | Names a real situation, not "I'm the kind of person who…". |
| A result | Each story ends with what happened, ideally with a number or a clear before and after. |
| "I", not only "we" | The interviewer can tell what you did. |
| Length | Most answers 1–2 minutes. |
| Filler words | Count them in one answer. Fewer than five is fine; nobody speaks in perfect sentences. |
| A clean ending | You stop when you've finished, instead of trailing off with "…so yeah". |
| Eye line and energy | You look at the camera or the imaginary interviewer, and you sound interested in your own story. |
Write down one thing to keep and one thing to fix. Just one of each. Fixing seven things at once fixes none of them.
Step 5: Redo your weakest answer straight away
Pick the answer that made you wince and do it again, right now, using your one fix. The second version is almost always noticeably better, and that improvement is what sticks. If the problem was the story itself (no result, unclear role, too long), rebuild it first with the STAR story builder, then say it out loud again.
How to make solo practice feel real
The hardest part of practising alone is that nothing surprises you. A few ways to add surprise back:
- Shuffle the questions. Write twelve on cards and draw six.
- Ask yourself the follow-up. After each answer, add one of the questions interviewers love: "What would you do differently?", "What did you do, specifically?", "Can you give me another example?"
- Use the company's own words. Take a value or priority from the job ad and ask yourself how you've shown it.
- Practise the awkward bits too. Mock the first two minutes (hello, small talk, "did you find us OK?") and the last two ("we'll be in touch"). They're more awkward than the questions.
- Increase the difficulty. Second time round, cut your time limit by 30 seconds per answer.
Alone or with a friend?
| Alone | With a friend | |
|---|---|---|
| Availability | Any time, as often as you like | When they're free |
| Pressure | Lower | Higher, which is closer to the real thing |
| Follow-up questions | You have to ask yourself | They can surprise you |
| Honest feedback | Your recording doesn't flatter you | Friends tend to be kind rather than useful |
The best setup is both: solo mock interviews to get your stories into shape, and one run with another person before the big day. Give your friend the six questions, three follow-ups to choose from, and one instruction: "Tell me one thing that worked and one thing to fix, and don't be nice about it."
If you'd like a second opinion from someone who works in your field, you can ask an expert on Provitude.
Five mistakes that make mock interviews useless
- Memorising scripts word for word. You'll sound like you're reciting, and one unexpected follow-up will knock you off track. Know your stories; don't memorise sentences.
- Only practising the questions you like. The curveball is the one that needs the practice.
- Stopping to restart. In a real interview, you can't. Practise recovering instead.
- Skipping the review. Answering out loud helps. Watching it back is where most of the improvement comes from.
- Doing it once, the night before. Do one mock interview a few days before, fix things, and do a shorter one the day before.
A simple plan for interview week
| When | What |
|---|---|
| 5 days before | Research the company and the role. Pick your six questions and your stories. |
| 4 days before | Mock interview #1 (30 minutes). Note one fix. |
| 3 days before | Rebuild your weakest story. Time your opener with the pitch timer. |
| 2 days before | Mock interview #2 with six different questions. |
| The day before | A short run: opener, one story, your two questions. Then stop and rest. |

Frequently asked questions
What is a mock interview?
A practice interview that copies the real thing as closely as possible: real questions for the job, answered out loud, under time pressure, followed by honest feedback. You can do one with another person or on your own with a recording.
How long should a mock interview take?
About 30 minutes works well: 5 to set up, 15 to answer six questions, and 10 to review and redo your weakest answer.
How many mock interviews should I do?
Two before an important interview is a good minimum: one to find the problems and one to check you've fixed them. More helps if the role is a big step up or you haven't interviewed in years.
Can I do a mock interview online for free?
Yes. You can record yourself on a phone, or use Provitude's practice sessions, which give you profession-specific questions, a mock mode with a timer and no hints, and a review at the end. Free and private by default.
What questions are asked in a mock interview?
The same ones you'd expect in the real interview: an opener like "tell me about yourself", a motivation question, two or three behavioural questions, one or two questions specific to the role, and a curveball.
