Overview
About game theory logic questions in quant interviews
Game Theory Logic is one of the highest-frequency categories in quant interviews. Jane Street, Optiver, and SIG lean on this material because it filters candidates fast: if your reasoning under uncertainty is shaky, the rest of the interview rarely recovers. The 44 game theory logic questions on this page are sequenced from easy to hard so you can build pattern recognition before facing problems with deliberate ambiguity. Most interviewers reuse the same handful of setups, so the goal is to identify the structure within seconds, not to invent a solution from scratch.
