How I turned interview rejection into a product — honest founder story

Hey Product Hunt community 👋 I want to be honest about why I built Prepedge because the story is embarrassing and probably familiar. I spent months grinding LeetCode. I knew the patterns. I could solve mediums in my sleep. Then interview day came. I froze. Not because I didn't know the answer. Because I had never actually practiced under real pressure with someone — or something — giving me honest feedback on exactly what I said. Practicing alone gives you false confidence. You fill in your own gaps without realizing it. Nobody tells you that your explanation was unclear, that you skipped the edge cases, or that you lost the interviewer at minute 3. That gap is what Prepedge fixes. What Prepedge does: 🎯 Simulates real interview pressure — not comfortable solo practice 💬 Gives specific feedback on exactly what you said — not vague "communicate better" advice 📈 Tracks your growth across sessions so you know exactly where you stand 🔍 Pinpoints your weak spots before the real interview does Who it's for: Developers who are serious about landing their next offer. Not beginners looking for tutorials — people who know their stuff but keep stumbling when it actually counts. Where I am right now: This is an early soft launch. The product works. The feedback loop is real. But I'm still building and I genuinely want to know: What's missing? What would make you actually open this over your current prep routine? What's the one thing that made your worst interview experience so bad? I'm here to answer everything. No pitch mode — just a developer who got frustrated enough to build something. 🔗 prepedge.online Drop your thoughts below. Brutal feedback welcome. 🙏
