HR phone screen, a hackerrank take-home, followed by a four-hour back-to-back virtual onsite (one technical, one case, one behavioral and one system design). The behavioral and the case questions are the same as the ones in other glassdoor reviews. The technical is a leetcode easy. The system design is the hardest but the interviewer was kind enough to allow any approach (front-end to back-end or vice versa, OOD, high-level, UI design, etc).
Interview questions [1]
Question 1
Pros and cons of a bank acquisition.
Binary search.
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
