FAQ

Common questions

How realistic is the AI interviewer?
Each AI persona follows the interview structure used at its respective company — intro, problem presentation, clarification, approach discussion, coding, testing, and complexity analysis. They adapt to your responses and push back when needed.
What programming languages are supported?
Python, JavaScript, Java, and C++. Code runs in a sandboxed environment with instant feedback on test cases.
How long does each interview take?
Paid interviews are 45 minutes — the standard length for a real FAANG coding round. Free trial interviews are 20 minutes.
Do credits expire?
No. Credits never expire. Buy them when you need them, use them whenever you're ready.
Can I use this on my phone?
The landing page is mobile-friendly, but the interview room requires a desktop browser with a microphone for the best experience.
How is the scoring done?
After each interview, our AI evaluates you across 5 dimensions: problem solving (30%), code quality (25%), communication (20%), technical knowledge (15%), and testing (10%). You get an overall score, a Hire/No-Hire recommendation, and detailed feedback for each dimension.
