The process took 2 weeks. I interviewed at Capital One (Fairfax, VA) in Mar 2021
Interview
Online Coding Test then four round powerday
Case Study and Debugging
Architecture and System Design
Behavioral
LeetCode Algorithms
Felt pretty well about everything apart from the algorithm problems as I didn’t run any code in the hankerrank coding pair. It also couldn’t use my preference of language as it wasn’t supported. It could have easily been solved with regex but you can’t look anything up. Also a very bad interviewer for that round, they were silent the entire time and not interactive. Didn’t seem like they wanted to be there. You have to be lucky on the interviewers.
It’s also very exhausting. Please change it to be split over days. Not everyone can take the time out of work for 4-5 hours of straight interviews
Interview questions [6]
Question 1
Design an application that handles smart meter readings for an apartment building, with the users being tenants and managers
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
Scheduled a call with recruiter. Recruiter didnt show up for the screening call and cancelled it 5 mins after the scheduled time. Dropped a follow up email and got no response. After a week, I got an email from the recruiter stating I am selected for the next round i.e Assessment. Sent me an email with the assessment description but no link. When I sent a follow up email asking for the link, I got ghosted again. It was a bad experience. Felt like she is toying with me. Why ghost an applicant repetitively? Unprofessional recruiter who doesn't respect an applicant's time or efforts!
