I applied online. The process took 2 weeks. I interviewed at Capital One in Sep 2023
Interview
power day 4 hours of interview that include one hour HR, one hour coding, one hour math question and one hour inteview with a product manager. The coding is easy and math question is a bit tricky
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]

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
