Had a call with the recruiter, then MC, and then Powerday! The Mini case is a smaller version of the Powerday Case. Make sure you are managing your time properly for all the cases. Practice well .
I applied online. The process took 4 weeks. I interviewed at Capital One (Cambridge, MA) in Dec 2025
Interview
2 recruiter calls and an initial technical screening, followed by Power Day, a 4 part interview session. 2 technical components, a case study, and a behavioral interview. They pretty much tell you details of each step before hand.
Interview questions [1]
Question 1
Design high level software architecture for a credit card banking system
The first step in the process is an online assmemt where you answer leet code questions and then they have an in person super day. if you do well, then they extend you an offer.
