INTERVIEW OVERVIEW
Flow Traders' interview loop tests quantitative reasoning and trading intuition, with mental-math screens and probability brainteasers as staples. Candidates typically need to demonstrate both numerical fluency and the ability to reason about market-making scenarios. QuantPrep's probability and expected-value problems are highly relevant; pair with ETF-specific context reading for the trading half.
FAQ
