Probability, expected value games, and staying calm under pressure

Trading

Source confidence: Official + candidate reports · Last reviewed: 7 Sept 2026. Exact process varies by role, office, and year.

SIG officially emphasizes strategic games, probability, odds, expectancy, and decision-making under uncertainty in its trading culture and candidate experience. Trading candidates report timed quantitative assessments, probability and expected-value interviews, and final-stage market-making or game exercises. Assessment formats vary: reports include both a 60-minute, 17-question Problem Solving Assessment and a shorter Quantitative Evaluation, including a 20-minute variant reported by a Chicago candidate in 2025.

Interview Rounds

Interview processes vary by role, office, seniority, and year. We separate official company information from candidate reports and third-party guides.
