Crack interviews before they happen.

Filter by company

Google, Meta, Amazon, Stripe — every problem in our library traces back to a real interview loop. Filter by the company you're prepping for and you'll see exactly the problems they ask. Some companies skew toward distributed systems, others toward product fit. We tag every problem with the loop it came from so the prep matches the room.

Match by difficulty

Random or specific

Voice in, sub-200ms latency

Speak naturally. The AI listens, transcribes, and replies in voice in under 200 milliseconds — fast enough that there are no awkward chatbot pauses. You don't have to wait for it to "think." It interrupts when you're rambling, the way a real interviewer does, and stays quiet when you need to think out loud.

Whiteboard or code editor

Pushback, not praise

5-dimension breakdown

After every session you get a per-dimension score: requirements clarity, scalability, trade-off reasoning, communication, and depth-of-design. Each dimension cites the specific moment in your transcript where it landed or fell apart, so you know what to keep and what to fix — not just an overall grade.
