What does the AI coach do?

It teaches one topic at a time. You name a concept, a pattern or a problem, and the coach explains it, then checks the explanation landed by asking you to apply it. It is a tutoring session, not an assessment: it stops to answer a question rather than marking you down for asking it.

How is it different from an AI mock interview?

A mock interview measures what you can already do under time pressure and reports on it afterwards. The coach works the other way round: it explains the idea first, adapts the explanation to the answers you give, and moves on only when the idea holds. Most people use the coach to learn a pattern and the interviewer to test whether it transferred.

Can I choose how it teaches?

Yes. A teaching style is picked before the session starts and shapes how much the coach explains up front versus how much it asks you to work out, and the choice is remembered for the next session.

Can it coach me through an actual coding problem?

Yes. A coaching session can open a problem from the catalogue, and code you write runs against real test cases in 6 languages, so the coach reacts to the behaviour of your solution rather than to a description of it.

Turn one confusing idea into a clear one.

Ask for a topic, pattern, or problem. Your coach will shape the session around that exact thread.

AI coach

An AI coach that teaches interview topics, one idea at a time

Thita's AI coach is a tutor for technical interview preparation. You bring a topic — a data-structure pattern, a system design trade-off, a behavioural situation — and the coach explains it, asks questions back to check the explanation landed, and adapts to the answers you give. It teaches; the AI interviewer tests.

How a session works

Name the thread. Search for a topic, a pattern or a specific problem, or type the question in your own words. A narrow prompt gets a more useful session than “teach me dynamic programming”.
Pick a teaching style. The style decides how much the coach explains before it asks you to try, and it is remembered for the next session.
Work through it together. The coach explains, then asks you to apply the idea. Coding topics open an editor and run your code against real test cases in 6 languages.
Keep the thread. Each session is recorded in your history with what was covered, so the next one continues rather than restarts.

What it covers

12 coaching tracks, grouped the way the catalogue is:
