Interview with the recruiter
I was sent to their interview funnel through CodeSignal.
I declined their code signal assignment (Their funnel) There are some companies making a living out these interview processes (Codesignal, Triplebyte, Hackerrank, etc)
Hiring companies (including Capital One) just send you to their standardized test and make you go through their 'funnel' (you are just another unit in their whole statistic).
To me I don't think companies are not doing a a good job assessing your real skills for the specific job. For example, the job that I applied for had little to do with the sample test that I saw on codesignal.
Additionally, because companies like Google, and Microsoft were successful early on by hiring 'solve the algorithm' type of engineer there are a lot of other companies assume that doing a similar process will make them hire the right candidate and be successful like those companies.
Don't buy into that, make them do better.
J'ai passé un entretien chez Capital One (McLean, VA)
Entretien
Interviewed for an engineer position, the interview was a joke. Asked basic OOP question with a few follow ups - no system design portion. Interviewer was very laid back and chill, didn't take it to seriously.
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.
