Ho sostenuto un colloquio presso Citadel (Chicago, IL)
Colloquio
No behavioral round. Very difficult technical interview. I don't think I explained clearly enough how I solved this problem, and the interviewer was apparently not satisfied with my response. Got rejected soon after the interview.
Domande di colloquio [1]
Domanda 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?
phone screen, then OA, then interview, asked the classic question "what's your biggest strength and weakness?", coding interview is 2 hard leetcode Dynamic programming. very difficult, no hint from interviewer
Normal interview process, not too lengthy, hr was very nice and replied to all my emails. The questions were a bit hard, and it needs some preparation before going into the interview.
