InterviewDen
Free AI mock interviews for SWE, IB, consulting, and quant
Paste a job description, pick a track, and an AI interviewer runs a live voice mock — coding, system design, IB technicals, MBB cases, or quant brainteasers. Unscripted follow-ups, scored written debrief, free with no signup. Built by a Berkeley CS student.
Hey Product Hunt — Paran here, former Citadel quant, CS grad from Berkeley and the maker of InterviewDen.
I built this because I burned ~$600 on mock interviews last recruiting cycle and the feedback was inconsistent, scheduling was a nightmare, and most platforms were SWE-only — my friends prepping for IB, consulting, and quant roles had basically no good practice option besides each other.
What InterviewDen does:
🎙️ Voice-first AI interviewer — it asks unscripted follow-ups, interrupts when you trail off, and grades on delivery (filler words, pacing) as well as content.
🧠 Five tracks: SWE coding + system design, IB technicals, MBB consulting cases, quant brainteasers, and behavioral.
📄 Tailored to any JD — paste a job description or LinkedIn URL and the interviewer adapts the questions to the role and firm.
📊 Scored written debriefs that don't evaporate after the call (Pramp's biggest weakness).
💸 Genuinely free. No credit card, no premium tier, no paywall. Unlimited mocks.
Who it's for: anyone interviewing for SWE, IB, consulting, or quant roles — students prepping for internship recruiting, career switchers, bootcamp grads, and people who can't afford $80/hr coaching.
What I'd love from PH: Try the track that's hardest for you and tell me where the AI is wrong, weak, or weird. Quant and IB tracks especially — those rubrics need the most calibration.
