Hey Product Hunt 👋 What inspired this: I kept watching people around me prep for interviews the same broken way — grinding LeetCode alone, watching "how to answer system design questions" videos, maybe getting one mock interview with a friend if they were lucky. Nobody was getting interrupted mid-answer with a real follow-up the way an actual interviewer does. You can know the material cold and still freeze the first time someone pushes back on your answer live. The problem: Most prep tools I found were either static quizzes, or covered just one round type — only coding, or only system design, never all three together. So people were stitching together three different tools before a real interview, with none of them actually simulating the pressure of a live back-and-forth. How my approach changed while building this: Started out thinking the hard part would be the AI logic — getting good questions, good feedback. Turned out the harder problem was making it feel like an actual conversation. Early versions had multi-second gaps between you finishing a sentence and the AI responding, which killed the whole point. Ended up rebuilding the entire pipeline around streaming instead of waiting for each step to finish before starting the next — transcription streaming in while you're still talking, the response starting before the full transcript even lands. Got round-trip down under 800ms, which is the difference between "talking to a bot" and something that actually interrupts you like a real interviewer would. That's Elan — coding, system design, and behavioral rounds, one AI interviewer, real follow-ups, and a rubric-based breakdown of what to work on afterward instead of a vague score. Solo building this end to end. Would genuinely love your feedback, especially if you've done technical interview prep recently — what worked, what didn't, what you wish existed. I'm here all day answering questions.
