Susquehanna (SIG)

Prop / Market Maker · Options market maker (game-theory driven) · Bala Cynwyd, PA

Poker and game theory are part of the culture, expect heavy probability, expected value, and reasoning under incomplete information.

Difficulty: ●●●●●

SIG is an options market maker built around game-theoretic decision-making. It famously teaches interns poker as a vehicle for reasoning about EV and uncertainty.

The interview leans hard on probability and expected value; the poker element is more a culture/decision-making theme than a single scored exam.
