      Software Engineer Interview

      Dec 6, 2018
      Anonymous Interview Candidate
      Nottingham, England
      No offer
      Positive experience
      Difficult interview

      Application

      I applied through a recruiter. The process took 5 weeks. I interviewed at Capital One (Nottingham, England) in Nov 2018

      Interview

      There was a screening code test on HackerRank, which failed to work multiple times, but was progressed onto next stage anyway. so cant say much about that, from what i could see looked like basic array manipulation Phone interview with hiring manager, just general questions about experience and more detail about the job and job fit. Then face to face interview which contained 4 parts - Job fit - White board system design - behavioral - paired programming All of which were in a somewhat relaxed atmosphere. Feedback I received was interesting, apparently they felt I was somewhat "bluffing" which was slightly offensive, not sure how this was founded as any question they asked to dig deeper was answered. They were critical having to probe for more information despite following the suggested STAR method and not knowing what was on their structured answer sheet. Felt like hacker rank failing to work, worked against me as the exposure they had to my development skills was limited to a 1 hour of paired programming, I had offered up code from some published apps I had written which would have shown 100's/1000's of hours of my coding effort instead, but they didn't really seem interested which I found weird. In the end there was a stronger candidate, so although I had "passed the interviews" the position was taken. Everyone I met through the day was super nice and welcoming, a somewhat enjoyable day really just a shame they felt like I was bluffing.

      Easy interview

      Application

      I interviewed at Capital One (McLean, VA)

      Interview

      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.

      Interview

      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.
