I applied online. I interviewed at Citadel (New York, NY) in Sep 2023
Interview
First round was a hacker rank coding assessment - your basic DSA questions. Then an interests form. Then an interview with one of their SWEs. I wasn't selected for further rounds despite perfectly answering all the interview questions (as told by interviewer himself), so not sure what happens next.
Interview questions [1]
Question 1
Why Citadel. and not (for example) Jane Street, Google or Goldman Sachs?
How would you solve a scheduling issue given a DAG of tasks and k computers? What if k is one or infinity?
Hard. Ask advanced python questions. 2 coding questions (1 easy 1 medium). Interviewer was friendly. Ask some resume questions (what project related to python that you are most proudest of, explain that...)
Went pretty well. They told me to introduce myself, asked me a question about my resume and then asked a LeetCode Medium question. I did not move forward to the Superday round.
The interviewer was incredibly rude and did not pay attention to my thought process and coding. The interviewer was looking down the entire time as I coded and muted himself right after he pasted the coding problem .
