Practice FAANG-style mock coding interviews with AI feedback
The AI asks clarifying and follow-up questions the way a real interviewer would, testing how you think rather than only what you type.
Write, run, and debug code in the session while narrating your approach, mirroring the conditions of an actual technical interview.
Every session follows Clarify → Design → Code → Test so you internalize the rhythm top companies expect.
Feedback focuses on communication clarity, decision trade-offs, and code quality, not just pass/fail correctness.
