Best AI Mock Interview Sites & Tools 2026

Being great at your job won't be enough to get you that coveted role at a top company. You need strong interview skills, and the best way to improve is through mock interviews.

Preparing on your own helps you brush up on your fundamentals, but you won't know how well you perform under pressure unless you practice answering questions out loud.

We understand that not everyone has industry connections or the budget to book an expert for every practice session. That's where AI mock interview sites come in.

To help you find the best tool for your needs, we've put together a curated list of the best AI mock interview sites and tools you can explore. We'll also explain when it's worth practicing with an expert instead.

1. Are AI mock interview platforms worth using? ↑

Yes, AI mock interview platforms are worth using, as long as you treat them as one part of your prep. AI mock interviews won’t replace practicing with an experienced interviewer, but they fill the gap between preparing alone and doing a live mock.

Practicing with an AI mock interview tool can help you:

• Ease into live practice. An AI interviewer asks you questions out loud and follows up on what you say, much like a real interviewer. It gets you used to thinking on the spot before you practice in front of a coach.
• Practice on your own schedule. An AI mock interviewer is ready whenever you are, and every minute of the session is spent working on your answers. 
• Retry a question as many times as you like. Once you see your score, you can answer the same question again straight away. 
• Practice with interview tools. Some AI interview platforms give you a shared whiteboard or a code editor. It’s usually similar to the ones you'll use in a real interview.
• Review your answers. Many tools save a transcript or recording that you can go back to after the session.

AI tools work best alongside peer and expert mocks. Use them to fix problems like rambling or vague answers on your own, so your sessions with people can focus on whether your answers would pass the real interview.

AI feedback isn’t always reliable, either. These tools can make things up and present them as facts. You’ll realize that a model answer may contain mistakes and, in some cases, a weak answer may get a strong score. Double-check anything that seems off before you build your prep around it.

2. Best AI mock interview sites and tools (2026) ↑

To help you kickstart your search for the best AI mock interview tool, we've researched the best tools based on value for money, the types of interviews they cover, the quality of their feedback, and customer reviews.

For your convenience, we’ve included tools for tech, product management, consulting, finance, and behavioral interviews. Several of them are free or let you try a session before you pay.

2.1 Interviewing.io AI Interviewer - Best free AI mock interview for coding ↑

Interviewing.io is best known for anonymous mock interviews with engineers from companies such as Meta and Google. Its AI Interviewer is the free version of that experience. In place of an engineer, an AI takes you through coding or system design questions the way a FAANG interviewer would.

The coding questions come from Beyond Cracking the Coding Interview, a book co-written by interviewing.io’s founder, Aline Lerner. When you start a session, you choose the topics and difficulty you want to practice, such as medium-level graph problems. The AI then picks problems from the book that match those specifications.

At the end of each session, the AI gives you feedback on your answer. The site doesn’t explain how it scores you, though, and nobody has reviewed the tool publicly yet, so judge the feedback for yourself after a session or two. 

You’ll also need an account to use the platform. But sign-ups have been limited to particular regions in the past, so check that it’s available where you are.

If you’d rather practice with a person, interviewing.io’s human mocks are anonymous and start at $179. On IGotAnOffer, sessions with a coach start at $100. Plus, you can choose your coach based on their background and reviews. 

Read our interviewing.io review for a closer look at the platform.

2.2 Hello Interview - Best AI mock interview for system design ↑

Hello Interview's Live Practice tool runs a 35-minute system design interview with an AI interviewer. You talk through your design out loud while drawing on a shared whiteboard. Then, the AI reads your board and asks follow-up questions.

Before you start, you choose the level you’re interviewing for ( staff engineer). The AI then judges your performance against that level and tells you whether it would lead to a hire or no-hire decision. You also get ratings for problem navigation, solution design, technical excellence, and communication.

Hello Interview ended its mentorship and live mock interview programs in May 2026. If you want a live interviewer to review your design, you’ll need another service, such as IGotAnOffer’s system design mock interviews.

Check our Hello Interview review for more details on the platform.

2.3 StrataScratch - Best AI mock interview for data science ↑

StrataScratch’s AI mock interviews are designed for data roles. Before you start, you choose your role, your target company, and how difficult the questions should be (easy, medium, or hard). If you’d rather skip the setup, the quick start feature gives you two medium-level SQL questions in 60 minutes.

Each mock uses AI credits, which also pay for StrataScratch’s AI chat and answer grading. The monthly and yearly plans include 1,000 credits a month, which StrataScratch estimates is enough for about five mock interviews. If you practice more often, extra credits cost $5 per 1,000 credits.

2.4 Prepfully AI Interviewer - Best for PM-specific practice ↑

Prepfully’s AI interviewer is built around specific companies. For PM roles, you choose the company and the round, such as Meta’s product sense interview, and the AI asks you a question in that style. You don’t need an account to start.

When the session ends, you get a scorecard covering more than 20 hiring criteria and a model answer to compare with your own. The transcript is searchable, which makes it easy to find the moments you’d answer differently next time.

Sessions are 15 minutes long, which is short for a PM interview. You’ll get practice structuring an answer for a particular company, but not much time with the deeper follow-up questions a real interviewer would ask. 

Read our Prepfully review to learn more about the platform’s services.

2.5 CaseTutor - Best AI case interview platform ↑

CaseTutor’s AI interviewer runs case interviews by voice, using a library of 75+ cases across different industries and difficulty levels. During a case, you’ll interpret timed exhibits (such as charts and tables) while the interviewer pushes back on your reasoning.

The subscription also includes simulations of the firms' screening tests, such as McKinsey's Solve games and Bain's SOVA test. 

To help you prepare for questions about your background and why you want to work in consulting, a tool called Story Studio lets you build your answers and rehearse them in a voice interview.

CaseTutor doesn’t offer human coaching. If you want a former consultant to review your performance, you’ll need another service, such as case mock interviews on IGotAnOffer.

2.6 IB Flash - Best AI mock interview for finance roles ↑

IB Flash is an AI interviewer for finance roles such as investment banking, private equity, hedge funds, and equity research. You answer by voice with your webcam on, and the AI asks follow-up questions based on what you say. 

If a mock shows you’re shaky on a topic like valuation, your subscription also includes flashcards and spreadsheet modeling tests you can use to practice it. IB Flash keeps track of the topics you keep getting wrong across all its tools.

The Starter plan comes with 4,000 credits a month and the Pro plan with 10,000, but IB Flash doesn’t say how many credits an AI mock interview uses. Pro does include unlimited mock interviews.

None of the finance tools we reviewed let you practice a stock pitch. For hedge fund and asset management interviews, you'll get more from a mock with a finance interview coach.

2.7 Interviews by AI - Best AI tool for behavioral interview practice ↑

Interviews by AI is a platform for roles in fields such as software, product, marketing, sales, design, and more. You can paste in a job description to get questions that match the role you’re targeting, or add your own. Then you answer out loud or type your response.

Once you’ve answered, the AI scores your response and shows how well it follows the STAR (situation, task, action, result) method. If your stories tend to run long or never get to the result, the feedback points it out.

Interviews by AI works well for streamlining your answers, but the site doesn’t say whether the AI asks follow-up questions. It may also not be able to tell you whether your stories fit a company’s culture. Amazon, for instance, judges behavioral answers against its Leadership Principles.

An expert coach can help with both. They’ll ask the follow-up questions a real interviewer would, and if they’ve interviewed at your target company, they can tell you whether your examples match what it looks for. 

If you’d like to practice with a coach who knows your target company, you can book a behavioral mock interview on IGotAnOffer.

3. When to use AI mock interviews and when to practice with an expert ↑

AI mock interviews are great for early practice. Still, they can’t replace a mock with a human interviewer. They can’t recreate the pressure of a real interview and also can’t tell whether your answer would pass at your target company.

Here’s how to decide which type of practice you need.

3.1 When to use AI mock interviews

Use AI mock interviews when:

• You’re early in your prep. AI tools cost less than expert mocks and more readily available than peer mocks. Meaning, you can practice a long list of questions on your own while you’re still learning the format.
• You know the answer but struggle to explain it. Answering out loud and then reading the transcript shows you where your explanation gets unclear or skips steps.
• You want to work on your delivery. AI tools flag filler words and answers that run too long so you can track whether you’re improving.

Once your answers are well structured, it’s time to test them with an experienced interviewer.

3.2 When to practice with an expert

Book a mock interview with an expert when:

• You get interviews but don’t get offers. Companies rarely tell you why you were rejected, but an experienced interviewer can show you which answers are weak and why and more importantly they can give you advice on how to improve.
• You want to practice handling pushback. An AI tool’s feedback isn’t always reliable, and it rarely pushes back the way a real interviewer does. An expert will question your answers on the spot, which prepares you for follow-ups during actual interviews.
• You’re targeting a specific company. If you can find a coach who has interviewed candidates at your target company, you can get insight into what its interviewers look for and can request a mock that matches its format.

If any of these apply to you, you can book a mock interview with an expert on IGotAnOffer.

3.3 IGotAnOffer - Best for live mock interviews with experts

IGotAnOffer has more than 450 coaches for tech, product management, consulting, and finance interviews. Many have worked at top companies such as Google, Meta, Anthropic, and McKinsey, and have interviewed candidates for the roles they now coach.

With that many coaches, the platform has filters to help narrow your search. Start with the role and company you’re interviewing for, then add a keyword if you want something more specific. You can also sort coaches by job offer rate if you want to see whose clients have had the most success.

Once you’ve got a shortlist, each profile shows the coach’s background and what past clients said about them. Some coaches also have a SuperCoach badge next to their name. IGotAnOffer reviews every coach’s track record each quarter and only gives the badge to coaches with an average rating of 4.9, at least five completed sessions, and few cancellations or reschedules.

To book a mock interview, you'll first need to buy credits. Each credit starts at $50, and coaches cost 2, 3, 4, or 5 credits per 1-hour coaching session. If you don't find your first session helpful, you can get a full refund within 24 hours.

Most sessions are a 45-minute mock interview followed by 15 minutes of feedback. Let your coach know which round you want to practice when you book, whether that’s system design, a case interview, or something else. And if your target company lets you use AI in its coding interviews, like Meta’s AI-enabled coding round, you can book an AI-assisted coding mock interview to practice that too.

4. FAQs about AI mock interview sites ↑

4.1 Do I need to pay for AI mock interviews?

No. Most AI mock interview tools on this list offer a free session or trial.

But for best results, you should combine these free sessions with mock interviews with an expert in your field, who can give you better and more constructive feedback.

4.2 Is it cheating to use AI to prepare for interviews?

No. Practicing with an AI mock interview tool is no different from practicing with a friend or a question bank.

4.3 How many AI mock interviews should I do?

There isn't a fixed number that suits everyone. Keep practicing until your feedback stops flagging the same problems. After that, we highly recommend booking a mock with an expert to check whether you’re ready for a real interview.

Are you ready for your next interview?

There's no perfect roadmap, but if you keep practicing deliberately and learning from feedback through mock interviews, you'll be well on your way to acing your next interview.
