Inside a session

15 minutes that show you
what the real thing feels like.

Every AI mock interview follows the same format as a real technical interview. You pick a topic, get a problem, solve it live while the AI interviewer watches, talks, and pushes back. Then you get a scorecard.

This is what a real session looks like, minute by minute. The green dots are things you did well. The yellow and red ones are what cost you points.

Voice AI

Not a chatbot.
A voice conversation.

Your AI mock interview is a live two-way voice call over WebRTC. You speak naturally, Alex responds in real time. It asks clarifying questions, challenges your reasoning, and gives hints when you ask. Sub-100ms latency so it actually feels like talking to a person.

✓Bidirectional voice, not text prompts
✓Follows up based on what you actually said
✓Adapts difficulty from junior to staff-level
✓Say "can I get a hint?" and Alex helps

Real code editor

The same editor
you use every day.

Monaco Editor, the engine behind VS Code. Syntax highlighting, autocompletion, live execution with real test cases. 16 languages. The environment you practice in during your mock interview is the one you'll perform in.

✓16 languages including Python, Go, Rust, Kotlin, Swift
✓Live code execution with test results
✓Starter code for every problem
✓Paste detection: Alex notices and asks about it

Detailed scorecard

Find out exactly
what cost you the offer.

Every AI mock interview ends with a full debrief. Five dimensions scored. Written feedback on the specific moments that lost you points. The things a real interviewer notices but never tells you, because they've already moved on.
