HR, technical 1, technical 2, easier than regular citadel coding interviews. questions related to resume ~15min, implementing functions in a class ~30min. Make sure to prepare this type of questions and you will get it. I didnt prepare for this kind of questions.
I applied through a recruiter. I interviewed at Citadel
Interview
I was reached out by a recruiter to interview for a contractor position on a trading team. The question they asked was strange and nothing to do with the position.
Interview questions [1]
Question 1
Convert a string to an int without using Java library.
First did OA and only passed 1/2 questions, where the first one was probably a leetcode medium and the second one was an easy. Then got first round interview, which I havent done yet.

Question 1
1st OA questions was I think a search problem and 2nd OA question was a dp problem.
The technical round kicked off with a query about choosing models for trading tasks, which felt straightforward. Then I tackled a problem analyzing correlations and generating Gaussians. The interesting part was recognizing the prompt instantly — it was the same question I had worked through on prachub.com during my prep. Overall, the interviews moved quickly, with a positive vibe throughout, and I felt confident enough to accept the offer when it came through.
