I built ReviewIQ after noticing a gap in how developers prepare for interviews. We practice writing code constantly. LeetCode, projects, system design, algorithms. But when someone puts an unfamiliar pull request in front of you and asks, “What’s wrong with this?”, that’s a different skill. I wanted a way to practice exactly that. So ReviewIQ gives you a realistic PR with 3 planted bugs. You review it, submit what you found, and get feedback on what you caught and what you missed. The interesting part now is seeing what happens with real users: which bugs consistently get missed, whether experienced developers approach the reviews differently, and where the exercises are too easy or unrealistic. If you try one, drop your score here. I’m curious to see the distribution.
