I applied online. The process took 4 weeks. I interviewed at Capital One (Richmond, VA) in Jan 2020
Interview
Comfortable interviews, everyone is very friendly. Three parts to the interview: case study, job fit and behavioral. Case study is math based. Job fit is to know your interests and career goals. Behavioral is pretty typical. All are one on one interviews that last 45 minutes. How much time you have at the end to ask questions depends on how long your interview lasts.
Interview questions [4]
Question 1
Describe a challenge you faced and how you overcame it?
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.

Recruiter screening to begin with. Then, technical discussion about java, spring boot, design pattern, small coding tasks and followed by design assessment for distributed systems. Finally, managerial round for the team fit
