The Quantlab Financial interview funnel
1. Coding / Quant Screen
Candidate-reported · algorithmic coding + mathAn early screen mixing algorithmic coding with quantitative reasoning. Candidate-reported items include a matrix-transpose implementation, correlated-random-variable generation, a simple ODE (u' + u = c(t)), and probability warm-ups. Treat it as a fundamentals filter before the markets-heavy interview.
2. ETF & Trading-Knowledge Interview
Candidate-reported · ~45-60 min · conversational with a trader/researcherQuantlab's signature round walks through a real instrument, classically an international ETF whose underlying trades in another time zone. How do you PRICE it while that market is closed (ADRs, futures as proxies)? HEDGE it (regression hedge)? QUOTE it as a market maker; why a premium over fair value? What if inventory keeps building? Reason aloud; they push back.

3. Final / Onsite
Candidate-reported · fit + deeper technicalA closing onsite / fit round that revisits your reasoning and research depth and checks whether you'll thrive on a small prop-trading floor. Candidate-reported specifics are limited; be ready to go deeper on any earlier answer and to talk through a project end-to-end.
