Show HN: I built an AI-powered technical interview prep tool

LeetCode wasn't actually preparing me or anyone else for the pressure of a real technical interview. Most platforms just give you a text box and a compiler. I wanted something that actually simulates the back-and-forth of an interviewer pushing you on time complexity, asking follow-up questions, and pointing out edge cases you missed. > The Stack: I built the backend with nestjs, prisma, postgresql, Webrtc for real time back and forth con and [socket.io] events in panel like code run etc…. claude-haiku-4-5 for con and anthropic.claude-sonnet-4-6 for interview scoring.
