Hey, Product Hunt, 👋 I’m Yashwanth, the maker of PrepLinx. I built this as a solo founder after struggling to find a realistic way to practice interviews that felt like talking to a real person, not just reading questions on a screen. What is Preplinx? Preplinx is an AI mock interview platform where you speak naturally, and the AI speaks back to you. You can practice coding, system design, and behavioral interviews, and get instant feedback on both your answers and your communication. Who is it for? Students who want to practice for campus placements or internships Job seekers switching roles or preparing for FAANG-style interviews Bootcamp grads who want unlimited, judgment-free practice Why I built it I saw people around me and including me freeze in real interviews because they only practiced on LeetCode or text-based tools. Talking out loud, structuring answers, and staying calm under pressure are hard to train alone, so I wanted a way to simulate a real interviewer 24/7, with honest feedback each time. What you can do today Start a voice-based mock interview in seconds Choose coding, system design, or behavioral rounds Get AI feedback at the end of each session I’d love your feedback on: How natural the interview conversation feels Whether the feedback is actually useful What you’d need to trust this for “real” interview prep Thank you for checking out Preplinx and for any comments, ideas, or brutal truth you’re willing to share. I’ll be here all day replying to everyone. 🙏
