Citadel interview questions

Interviewed during Fall 2025. After passing resume screen, HR will send an online assessment. This assessment will consist of a couple easy-med difficulty python and sql data analysis problems. After the OA, there are 3 virtual interviews for around 45 minutes. Each interview will be centered around your resume and relevant work or project experience with the internship. The technical questions are derived from your resume, so expect statistic and data science concept questions you should be familiar with. All the interviewers are really nice and professional. After these rounds, the onsite consists of 3 45 minute interviews with team leads with again fit and technical questions related to your experience, followed by one final interview with the CIO of one of the 5 strategies you will be placed in. This one was purely fit and behavorial, and mostly just about questions you have. Did not get offer after this.

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.
