I applied online. The process took 4 weeks. I interviewed at Capital One (Reston, VA) in Oct 2021
Interview
Power-Day, which comprises of Case Study, Behavioral, and a Technical.
Case Study: Look at some code and tell them what it's doing, this was the only enjoyable part of the interview.
Behavioral: Bunch of "Name a time when..." This was probably the most uncomfortable interview ever and the interviewer was not friendly when struggling to find an example for certain questions. I did great on my technical and case study but this interview really just frustrated me. The case study felt more of behavior than this interview.
Technical: 2x LC Mediums
Interview questions [1]
Question 1
Case Study:
Look at some code and tell them what it's doing
Behavioral:
Name a time when you ran into a mistake.
Name a time when you were challenged
Name a time when you became a leader without being specifically told to be.
Technical:
LC Medium x2
Interviewed for an engineer position, the interview was a joke. Asked basic OOP question with a few follow ups - no system design portion. Interviewer was very laid back and chill, didn't take it to seriously.
Was not too difficult. three total interviews all on the same day back to back. technical one, behavioral one and a case which was more of just a debugging question
Expecting a challenging experience, I found the interview at Capital One to be intense, particularly during the system design section. The question on designing a rate limiter with a token bucket algorithm took me by surprise; mid-way through the problem, I realized it was very similar to a drill I’d practiced on prachub.com just days earlier. The technical rounds included several DSA questions, and the interviewers were thorough but supportive. Ultimately, I received an offer and happily accepted, feeling well-prepared despite the pressure.

Question 1
Design a rate limiter using a token bucket algorithm and discuss how it would handle bursty traffic and distributed deployments.
