FREE DEMO
Practice a realistic coding or system design interview with Alex, our AI interviewer.
Try a short one with me. It's free.
This is a free demo, not an interview credit — it runs shorter and covers less than a paid interview. You can use it once.
Both demos run shorter than a full session.
Compiled and run against the tests.

A free AI mock interview is a practice session where an AI interviewer simulates a real FAANG interview. You get a coding or system design problem, solve it in real-time, and receive instant feedback including a hiring signal and detailed scoring.
The coding demo is 20 minutes with one problem. The system design demo is 30 minutes with a URL shortener design. Both are shorter than paid interviews which run 50 minutes across two problems.
No. The free demo requires only a Google sign-in. No credit card or payment information is needed. You get one free coding demo and one free system design demo.
After the demo you receive a hiring signal (Strong Yes to No), 12-dimension scoring across code correctness, communication, DSA knowledge, and optimization. You also get a session recording to review.
Yes. The demo uses FAANG-style problems similar to what you would see at Google, Meta, or Amazon. For company-specific problems and full-length interviews, upgrade to a paid plan.
