What the Final tests

Conversational and values-oriented, confirming both technical bar and whether you'd thrive on CTC's floor. Expect a mix of lighter technical framing and culture-fit discussion.

How to prepare for the Final

Bring questions that show research. Ask about the desks, the QTA path, and how researchers and traders collaborate.
Restate your 'why CTC' clearly. Connect the market-making culture and Chicago floor to something specific about you.

Final-week checklist

STAR stories mapped to CTC's core values (teamwork, ownership, owning a mistake)
QTA primer reflexes: EV, conditional probability / Bayes, distributions, confidence intervals
Market-making intuition: fair value + credible spread + inventory management
Mental math without a calculator for the trading-game rounds
