Hi all, I am interviewing with Citadel for their Software Engineering Rotation Program. I have a phone screen scheduled next week. I have heard scary stories about Citadel's interviews being very hard and having questions that are not even on Leetcode. I am an international student applying for US positions so this is really important to me. Please, if you have had a phone interview with Citadel, can you share your experiences and any recommendation on how to prepare?
