Overview

About market microstructure questions in quant interviews

Market Microstructure sits at the heart of trader interviews at Citadel Securities, Optiver, and IMC. Unlike the math sections, these questions reward quick intuition over rigorous derivation: the candidate who quotes a tight spread in 20 seconds beats the one who derives the right price in five minutes. The 64 market microstructure problems on this page rebuild that intuition with realistic prompts, then stress-test it against the harder cases that determine whether you get a second round.
