I applied through an employee referral. The process took 3 weeks. I interviewed at Capital One (Richmond, VA) in Nov 2025
Interview
just like others have described, it's a 4 hour interview (1 hour case study, technical, break, behaviorial). Behaviorial is pretty standard, technical and case study honestly aren't that bad and definitely studyable. However, it's still pretty difficult and definitely study up. It's not like a leetcode.
