AI Mock Interview
Practise the interview before you sit it. This free AI mock interview asks the questions your actual job posting would produce, scores every answer, and tells you exactly what to fix, with no microphone, no camera and no sign up.
Practise the interview. Then walk in with the whole application.
JobFast reads the same job posting and writes your tailored CV, a matching cover letter and interview prep in one pass. Free to start.
Interview practice works, and almost nobody does it, because the honest version of practice means saying your answers out loud to someone who will tell you they were vague. This free mock interview does that part. Paste the job posting, choose how many questions you want, and answer them one at a time.
You get feedback after every answer rather than at the end: a score out of 100, what actually worked in your own words, what would have cost you the job, and the points a strong answer to that question would have hit. At the end you get an overall read and the one thing to change before the real interview.
How it works
- 1
Tell it what you are interviewing for
Add the role, and paste the job description if you have it. With the posting you get the questions this employer would realistically ask rather than generic ones.
- 2
Answer one question at a time
Say your answer out loud first if you can, then type roughly what you said. Rough is fine. Polished practice is not practice.
- 3
Read the feedback before the next question
Every answer is scored and broken down immediately, so you can apply the fix to the very next question instead of at the end.
Why mock interviews work
Interviewing is a performance skill, and performance skills do not improve by reading about them. The gap between knowing a good answer and delivering one under mild social pressure is enormous, and the only way to close it is repetition. Candidates who have said their answers out loud five times sound calm. Candidates who have thought about them sound like they are thinking about them.
The specific thing practice fixes is compression. Almost every unpractised answer is too long, and length is what makes interviewers stop listening. When you say an answer for the third time you naturally cut the setup, get to the action faster, and land on a result, which is the same shape a coach would have imposed on you.
The second thing it fixes is the surprise question. There are perhaps twenty questions that make up the large majority of interviews, and the reason a candidate freezes on one is almost never that it was unfair. It is that they had never once said an answer to it. Running through a mock interview turns unknown questions into questions you have simply answered before.
What this mock interview does differently
It is tied to your actual posting. Generic interview practice gives you generic questions, and generic questions are the easy ones. When you paste the job description, the questions come from the responsibilities and requirements in it, which is where the uncomfortable questions live.
It gives feedback after every answer rather than at the end. Feedback delivered at the end of a session is a report. Feedback delivered before the next question is something you can immediately apply, and most people visibly improve between question two and question four.
It requires no microphone, no camera and no account. Voice based simulators measure delivery, which matters, but they also mean you cannot practise on a train, in an office, or at eleven at night with people asleep in the house. Typing lowers the barrier to actually doing it, and the content of an answer is what most interviews are decided on.
- Questions generated from your real job posting, not a generic bank.
- A score and specific feedback after every single answer.
- Follow up questions when an answer is vague, the way a real interviewer would.
- No microphone, no camera, no permissions prompt, no account.
- Your session is saved in this browser, so a refresh does not lose it.
How to get the most out of a practice session
Answer out loud first, then type what you said. This is the single highest value habit available here. Typing an answer lets you edit as you go, which hides exactly the problem you are trying to find. Speaking it first exposes the rambling, the filler, and the moment you realise you have no ending.
Do not polish. The instinct is to write your best possible answer because it is being scored, and it produces a comfortable session that teaches you nothing. Type the mediocre answer you would actually give under pressure and let the feedback do its job.
Run it more than once. The first session finds the obvious problems, which are usually length and a missing result. The second session, run a day later with the same posting, is where you find out whether the fix stuck. Two sessions of five questions beats one session of ten.
Then say the corrected answers out loud again away from the screen. The feedback tells you what to change, and the change only becomes real when you have spoken the new version a few times.
The questions almost every interview contains
Every interview draws from a small pool. Tell me about yourself. Why this role and why us. Walk me through your background. A time you handled conflict. A time you failed or missed a deadline. A time you led or influenced without authority. How you handle competing priorities. What you are looking for next. And your questions for them at the end.
Preparing that list is not the same as preparing twenty separate speeches. Six well chosen stories, angled differently, cover most of the behavioural questions, and the rest are about your motivation and your judgment. A mock interview is where you find out which of your six stories collapses when it has to be told against a specific question.
For a technical or role specific interview, add the material of the job itself: the tools named in the posting, the situations that role deals with weekly, and the trade offs someone in that seat has to make. Choose the technical option in the setup and paste the posting to get those.
What interviewers are actually scoring
Specificity first. The difference between a good and a poor answer is almost always the level of detail: a named project, a real number, a decision you can explain the reasoning behind. Interviewers are trained to probe general claims, and general claims are what fall apart under a follow up.
Ownership second. Answers full of we leave a scorer unable to credit you for anything. Say we for the context and I for what you did, and be explicit when you led something.
Then structure and length. An answer that arrives in a recognisable shape, gets to the action quickly, and lands on an outcome is easier to score highly, and easier to remember at the end of a day of interviews. That is the entire reason frameworks like STAR exist.
Finally, judgment. The strongest answers include one line explaining why you chose what you chose. Outcomes can be luck. Reasoning is evidence.
- A named project, a real number, a specific decision.
- I for your actions, we for the context.
- Get to what you did inside the first twenty seconds.
- End on an outcome, stated plainly.
- Include one line of reasoning behind a decision you made.
Practising for a real interview in the next few days
If your interview is tomorrow, run five questions with your actual posting, fix the two biggest issues the feedback names, and say your opening answer out loud until it is boring. That is a genuinely useful hour, and it is far more valuable than rereading the company website again.
If you have a week, run a session every other day and change one thing each time. Length in the first session, specifics in the second, and the closing questions and your own questions in the third. Spacing practice out beats cramming it, for interviews as much as for anything else.
And prepare the questions you will ask them, since the interview does not end until you have answered that one. Our questions to ask the interviewer tool builds those from the same posting, so the whole conversation points at the same role.
This free AI mock interview online is unlimited and needs no account, so the only limit on practice is how honest you are willing to be in the answers you type.
Frequently asked questions
Is this mock interview free?
Yes. It is free to use with no sign up, no credit card and no paywalled feedback. Every question, score and summary is visible.
Do I need a microphone or camera?
No. You type your answers, which means you can practise anywhere, including places where speaking aloud is not an option.
How many questions does it ask?
You choose three, five or eight. Five is the usual sweet spot for a first session, and you can end early at any point and still get your summary.
Does it use my actual job description?
Yes, if you paste it. With the posting the questions come from the real responsibilities and requirements, which is where the harder questions are.
When do I get feedback?
After every single answer, before the next question. That way you can apply the fix immediately rather than reading a report at the end.
Will it ask follow up questions?
Yes. A vague answer gets probed the way a real interviewer would probe it, rather than being politely accepted.
Should I write my best answer or my realistic one?
Your realistic one. Say it out loud first and type roughly what you said. A polished written answer hides exactly the problems practice is meant to find.
Does it work for technical interviews?
For role specific and technical discussion, yes. Choose the technical option and paste the posting. It is not a live coding environment.
What if I get interrupted mid session?
Your session is saved in this browser, so you can close the page and pick it up where you left off.
How many times can I practise?
As often as you like, within a fair use limit that is sized for full sessions rather than single questions. Two shorter sessions on different days beat one long one.
Is what I type kept private?
Your session stays in your own browser and the start over button clears it. Answers are sent to the model only to produce the next question and your feedback.
What should I do after the session?
Fix the single thing the summary names, then say the corrected answers out loud away from the screen until they sound natural.
