PrepMaster: AI Interview Coach: Real-time speech feedback for interviews

Hi Product Hunt! 👋 I'm Ewan, the maker behind PrepMaster. As a developer and a non-native English speaker, I've always found job interviews nerve-wracking. I realized that reading interview tips wasn't enough—I needed to practice speaking. But practicing in front of a mirror felt weird, and mock interviews with tutors were expensive. So, I built PrepMaster to solve this. 🤖 It uses Voice AI to act as your personal interview coach. It asks you questions, listens to your answers, and gives you instant feedback on your grammar, fluency, and confidence. I'd love your feedback on: Does the AI voice interaction feel natural to you? What other interview scenarios (e.g., coding, behavioral) should I add next? Thanks for checking it out! I'll be hanging out in the comments all day to answer your questions. 🚀
