I applied online. The process took 3 weeks. I interviewed at Citadel (New York, NY) in Oct 2025
Interview
The interview process was straightforward and was not too hard. I first got sent a HireVue to complete with basic behavioral questions, then two leetcode style basic coding questions. Then they followed up with a video interview.
