Question 1
All three interviewers asked: tell me about yourself.
Two business cases, one conversational product skills interview for the power day. Make sure you study your typical case math because it's pretty quantitative, easy to trip up on your work
I applied online. The process took 4 weeks. I interviewed at Capital One in Aug 2025
Interview
First I got an online assessment (Codesignal GCA). I got 600/600 but have heard of others getting interview with as low as ~450. Then had a power day (4 hours for 1 behavioral 1 technical and 1 case interview + 1 hr break). Behavioral was standard & easy, technical was not too hard but just keep track of time. Case was not too bad either after studying ahead of time and running through several example cases.
