Practice anytime, no scheduling
AI Mock Interview — Free Practice That Actually Grades You
Stop waiting for a peer to be free. Run an AI mock interview in your browser: pick from 100+ real questions across coding, system design, behavioral, ML, frontend, DevOps, SQL, product and security, answer aloud or in text, and get an instant AI grade with specific feedback. No install, no signup — then take the live helper into real calls.
Why AI mock interviews beat the old way
Peer mock interviews mean scheduling, an awkward stranger, and uneven feedback. An AI mock interview gives you unlimited reps, instant grading, and zero coordination.
1. Unlimited reps, on your schedule
No booking, no time zones. Do five mock interviews at 1am if that's when you study. The volume of reps is what builds fluency — and the marginal cost here is zero.
2. Instant, specific grading
Answer, and the AI scores you with concrete feedback: did you reach optimal complexity, did your STAR answer land a measurable result, did you miss an edge case? It shows what a real interviewer would ask next.
3. Every track, real questions
113 real questions across 9 tracks: behavioral, system design, coding, data science/ML, frontend, DevOps, SQL, product, and security. Some hand you a buggy snippet to debug; you can attach a screenshot for the AI to grade against.
How it works (30 seconds)
| Step | What you do | What you get |
|---|---|---|
| 1. Pick | Choose a track + difficulty | A real interview question, read aloud |
| 2. Answer | Type or talk, attach a screenshot | A timed, realistic prompt |
| 3. Get graded | Submit | A score + specific feedback + the likely follow-up |
| 4. Go live | Download the app | Real-time help during actual interviews |
From mock to the real thing
The browser demo is the mock interview; the desktop app is the live copilot. Practice with the free demo, then when you have a real Zoom, Teams, or Meet interview, the app whispers structured help in real time — invisible on screen-share. See coding, system design, and behavioral help.
