Intervu

Intervu is the best place to prepare for system design interviews, built for engineers who know that reading articles and watching videos only gets you so far. Its AI has been trained on a massive volume of real system design interviews, so the experience it delivers feels genuinely close to the real thing — not a watered-down simulation.

You get unlimited interview simulations, each paired with comprehensive, actionable feedback that tells you exactly where you fell short and how to improve. Whether you're aiming for FAANG or just want to walk into your next tech interview with real confidence, Intervu gives you the reps you need to get there.
