It's a full day "power day." It gets overwhelming, for sure. I've heard that the worse you feel about it, the likely better you perform. It seems like the interviewing team has a set list of questions, and a lot of the questions are replicative.
Interview questions [1]
Question 1
Tell me about a time that you had to work with a difficult teammate.
I applied online. I interviewed at Capital One in Aug 2025
Interview
Superday was one case study, one behavorial, and one technical. Technical was just implementing a class, usually involving a hashmap. Case study was related to credit cards and you had to speak out loud and ask questions. Behavorial was typical.
1) Recruiter Screen
2) Online Assessment.
3) Power day interview.
After clearing the assessment got an email from recruiter of team matching, but in the meanwhile rejected my application. Didn't gave proper reason.
