Try a 3-question mock interview, no sign-up

Three questions, about ten minutes, nothing to create and nothing to pay. You get one coding problem — and the code you write is compiled and run against the same stored test cases the full product uses, not just read by a language model — plus one behavioural question and one system-design question. Each answer comes back with a score out of ten and one specific thing to fix. At the end you get a short report, and you can create a free account if you want to keep it.

AI mock interviews

AI mock interviews for coding, system design, data, product and behavioural rounds

Thita's AI mock interviews are live voice sessions: you speak with an AI interviewer that asks a question, follows up on the parts of your answer that are vague, runs the code you write against real test cases in 6 languages, and returns a written report when the session ends. It covers technical and non-technical rounds, it is available whenever you are, and it does not need a partner on the other side.

AI mock interview questions, answered

What is an AI mock interview on Thita?

A timed, spoken interview with an AI interviewer that asks a question, listens to your reasoning, asks adaptive follow-ups when your answer is thin, and reads the code you write in the browser. Code runs against real test cases in 6 languages — Python, C++, Java, JavaScript, Go and C# — so the interviewer reacts to what your solution actually does, not to what you say it does.

Is Thita’s AI mock interview free to use?

The Starter plan is free forever and gives you limited access to AI mock interviews, code feedback, and learning paths, so you can try a session without paying. Pro and Elite add a larger monthly AI allowance, and international users also get a 7-day free trial on those monthly plans.

Does the AI interviewer actually run my code?

Yes. Coding rounds open an in-browser editor, and every submission executes against the problem's real test cases in 6 languages — Python, C++, Java, JavaScript, Go and C#. The interviewer sees whether the code actually passed, not just what you said it does.

Which interview rounds can I practise?

Data structures and algorithms, high-level system design, low-level (object-oriented) design, data science, AI and machine learning, product management and behavioural rounds. The catalogue carries 51 interview roles and 23 round types, so a session can be scoped to the round a specific company actually runs.

Can I practise with my own resume?

Yes. A resume-based interview reads your experience and asks about the projects on it, which is how most first rounds and hiring-manager screens actually open.

Do I get feedback after the interview?

Yes. Every session ends with a written report: what the interviewer asked, where the reasoning held up, which follow-ups you missed, and how the submitted code behaved on the test cases. Reports are kept in your history so two attempts at the same pattern can be compared.

How is this different from practising alone?

Practising alone has no one to ask a follow-up when a claim is unjustified or a design has no failure mode — the AI interviewer does, in the same session where it also runs your code and covers non-coding rounds like system design, behavioural and product management.
