I applied online. The process took 2 weeks. I interviewed at Citadel Securities in Nov 2025
Interview
The interviewer dove right in to the problem after five minutes of introduction. Short and intense interview lasted 40 mins and then five minutes of general culture talk. To best of my ability I answered everything, I wonder what more could have I done to pass the round.
Interview questions [1]
Question 1
Random walk inspired problem which progressively kept on getting harder and focus on physical intuition
Direct technical. One coding, then behavioral asking technicals about background. coding was a leetcode hard, and the bevhaioral was second and went well, but ended here, so not sure what the screen was at behavioral.
There were two phone screenings followed by five more interviews in the onsite round. Was asked questions in probability, statistics, and programming. Also questions about my resume and previous research experience.
