I applied online. The process took 4 weeks. I interviewed at Capital One (Richmond, VA) in Jul 2018
Interview
2 phone interviews (recruiter followed by technical lead) and then a multi person on site interview. The process was extremely quick; first call to offer was about a month. The on site consisted of 4 one on ones with team members and ended with a case study style interview.
Interview questions [1]
Question 1
Hardest technical problem you've solved as an individual?
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.
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
