Three part interview. First, there is the classic technical interview, with LeetCode questions. Then there is the behavioral interview. Then there is the case interview, which, for me, was the hardest part of the interview.

Question 1
(Behavioral) Tell me about a project you're most proud of.
Codesignal -> Powerday (3 interviews). Behavior, Technical, and Case Interviews. One hour break within a four hour time frame. Can't really prepare for Case Interview just make sure to keep talking and explain thought process throughout.

Interview
First CodeSignal OA. Pretty standard 4 questions I answered 3 completely and got partial credit on the fourth. Then recruiter call where they ask you the standard questions about grad date, etc. Then "Power Day" where it's 3 60 minute interviews in a 4 hour window. These interviews are technical, behavioral, and business case.

I applied online. The process took 3 weeks. I interviewed at Capital One (Richmond, VA) in Sep 2025
Interview
The Powerday has 3 rounds: technical, behavioral, and a case study. Not specifically a LeetCode-type question for the technical, somewhere in between a LeetCode and system design, and it was pretty easy. Behavioral was pretty standard, with only 3 questions. The case study was also pretty easy if you knew basic coding and had basic business insights.
