面试风格
Citadel Securities has an extremely rigorous and selective interview process. Expect multiple rounds including algorithmic coding challenges, system design interviews, probability and statistics questions, and brain teasers. For quantitative roles, strong mathematical reasoning and problem-solving under time pressure are tested. Software engineering candidates face challenging data structures and algorithms problems, often at a competitive programming level. The process typically includes a HackerRank or similar online assessment, phone interviews, and a full virtual or on-site super day. Timeline varies but can be three to eight weeks. The acceptance rate is very low.
