The process took 1+ week. I interviewed at Capital One (Plano, TX)
Interview
Code signal followed by behavioral, technical, and case interview. The technical interviewer did not help me much. It felt like she was doing something else and was bothered every time I asked for clarification.
The behavioral interviewer was not impressed with my answers. He said they would give me some points for my answers, but not a lot. What can you do. I guess they expect everyone to give Mark Zuckerberg answers or something.
The case interviewer was nice and helped me. I think he was the only one that liked my answers.
I got the vibe that people were unfriendly at the company, since 2/3 of my interviewers seemed unsatisfied with me.
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.
Interview questions [1]
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
