What the SIG Quantitative Evaluation covers
Unlike the Optiver 80-in-8, which tests raw arithmetic speed, the SIG Quantitative Evaluation focuses on deliberate probabilistic and logical reasoning. You have roughly 4–7 minutes per question, and a calculator is allowed. The real differentiator is whether you can identify the correct approach — not whether you can compute quickly.
Questions follow predictable patterns: geometric distributions (expected rolls until an event), conditional probability (Bayes, conditional sample spaces), combinatorics (permutations, combinations, arrangements), expected value calculations, and the occasional logic or game theory puzzle. Problems typically have integer or fraction answers — decimal answers are almost never accepted on the real test.
SIG's poker culture means they specifically value candidates who can reason about expected value in terms of “would I play this game?” — not just compute the number. Practice connecting each calculation to a decision.
