I applied through an employee referral. The process took 3 months. I interviewed at Citadel Securities (New York, NY) in Nov 2022
Interview
Behavioral interview (phone) Technical interview (phone) About an hour phone call asking different types of questions about my interests, background, and what I know. It was pretty casual and I think to best prepare just be able to explain your experience and past projects in detail.
Interview questions [1]
Question 1
How do you compare regression models? What is going on with the Japanese Yen, how does it affect US Treasury Bonds? What's 144^2 in your head?
