Hey hunters! 👋
I'm building LeetQuant — think LeetCode, but for quant finance interviews.
When I started prepping for quant trading/research roles, I hit the wall everyone hits: the good problems are scattered across PDFs, forum threads, and books like the Green Book — and there's no way to track what you've actually mastered. You solve a brainteaser once, feel great, then blank on it three weeks later right before the interview.
So I built the tool I wished existed:
🧠 140+ original problems across 9 topics — brainteasers, probability, stochastic calculus, statistics, options/Greeks, portfolio, finance, and quant-flavored coding
🏷️ Tagged by firm — filter for Jane Street, Optiver, Two Sigma, Citadel, SIG & more
✅ Instant answer-checking + worked solutions + progressive hints — get it right, it's marked solved
🔁 Spaced repetition built in (Anki-style) — shaky problems come back soon, solid ones much later
🗺️ Role-based tracks + day-by-day study plans — Trader, Researcher, or Risk, with topics interleaved so nothing fades
📊 Progress dashboard — completion by topic, firm, and difficulty
It's completely free — no credit card, just sign in with Google and start.
I'm a solo builder still prepping myself, so it's a living project (native iOS app in the works 👀). I'd genuinely love your feedback — what topics or firms should I add next?
