I applied through an employee referral. The process took 1 day. I interviewed at Citadel (New York, NY) in Aug 2024
Interview
The interviewer asked about my background and then go straight to technical questions. One probability question, one stats question, and one algorithm question. Overall is fine but I did not answer some questions well.
Interview questions [1]
Question 1
There are three random variables, $X,Y,Z$. The three correlations between the three variables are the same. That is, $$\rho = \Corr(X,Y) = \Corr(Y,Z) = \Corr (Z,X)$$ What is the tightest bound you can give for $\rho$? How about the general case for $n$ random variables?
- Questions on Linear Algebra and Coding
- Discussion of a problem at the intersection of optimization and classical machine learning
- No behavioural questions or anything about my personality or work experience, the interview was purely technical

Start with my own self-introduction and the interviewer's self-introduction first for five minutes, then a couple of technical questions for like thirty minutes, and in the end, questions for the interviewers about the company.
I received the interview a few weeks after applying online. During the interview i was asked by the interviewer about my past experience and also some other related technical questions.
