I applied through an employee referral. The process took 2 weeks. I interviewed at Capital One (Richmond, VA) in Oct 2017
Interview
I applied through a referral and was contacted by a recruiter to schedule a phone call later that week. It was just a simple get-to-know-you phone call. After that, I was invited to the final interview on-site. This consisted of the 3 interviews have mentioned. Everyone I met at Capital One was friendly and open about their experience working there. I received an offer a few days after the interview.
Interview questions [1]
Question 1
Tell me about a time you explained a technical topic to a non-technical person.
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
