Free AI Interview Practice (2026): 9 Mock Interview Tools

Most people prepare for interviews by reading lists of questions, which isn't the same as answering them out loud. Reading an answer in your head feels fluent; saying it to a camera shows you where it wanders. AI mock interview tools fix that: they ask questions, listen to your answers and tell you what to tighten, from structure to filler words.

The nine tools below are listed alphabetically and in no particular order, and all come from smaller specialist companies. Each description comes from the tool's own website, re-checked today. When you're nearly ready, my guide to questions to ask the interviewer covers the end of the interview too.

AI interview practice tools compared

In the free plan column, Yes means the tool's own site describes a free plan, free tier or free practice, Trial only means a time-limited trial and No means neither is stated. Free plans often limit the number of mock interviews or feedback reports.

Questions a US employer shouldn't ask you

Here's a rule worth knowing as you practise. The EEOC says an employer may not ask a job applicant if they have a disability, or ask them to answer medical questions or take a medical exam before making a job offer, although it may ask whether they can perform the job and how.

What that means for you: if an AI mock interviewer asks about your health, don't spend time rehearsing an answer. In a real US interview, that question shouldn't come up before an offer, and you can steer back to how you'd do the job.

General practice, technical rounds and speaking coaches

General mock interview tools ask behavioural and role-specific questions, then score your answers for structure and relevance. Technical practice platforms focus on coding and system design rounds, often with real interviewers as well as AI. Speaking coaches listen to how you talk, highlighting pace, filler words and eye contact, which helps whatever the role.

Most candidates get the most from one general tool for content and one speaking coach for delivery. If you're changing career, spend extra time on the question about why you're moving, because it's the one interviewers return to and the one people tend to ramble on. Practise a short, positive answer until it feels natural. The same goes for gaps in your CV: one calm sentence about what you did and what you learned is far stronger than an apology.

A practice session that helps

1. Paste in the job description so the questions match the role.
2. Answer out loud, standing up, as you would on a video call.
3. Use a simple structure: situation, what you did, and the result.
4. Read the feedback and redo the weakest answer straight away.
5. Record yourself once to check pace and filler words.
6. Stop after half an hour and come back the next day.

Getting ready beyond the practice tool

• Research the company. Know what they sell and who their customers are.
• Prepare stories. Have three or four examples you can adapt to different questions.
• Use prompts to prepare. My ChatGPT prompts for job interviews help you build those stories.
• Test your set-up. Check camera, sound and lighting before a video interview.

Do you make an AI interview practice tool? Tool makers can ask to be considered for a featured place on this list.

My plain advice on practising interviews with AI

Start with a free tool that lets you paste in the job description, and practise the five questions you're most likely to get. Answer out loud every time; silent rehearsal feels productive and isn't.

Use the feedback as a guide, not a judgement on you. And for your final practice, ask a real person to interview you, because a human will react in ways no tool can.
