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.
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.
