Probability, expected value games, and staying calm under pressure
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.
Round 1:Quantitative assessment
Candidate-reported variants include 17 quantitative questions in either 20 or 60 minutes. Probability, combinatorics, logic, and mathematical problem solving recur, but the mix varies.
Round 2:Recruiter or first interview
Candidates report conversations about background, motivation, markets, and fit before or around the technical stages.
Round 3:Trader technical interview
Trading candidates report probability, expected value, odds, and decision-making questions.
Round 4:Final interviews and games
Candidates report expected-value, market-making, or bidding exercises involving cards, dice, or coins. The number and duration of rounds vary.
