      Software Engineer Interview

      Apr 7, 2019
      Anonymous Interview Candidate
      Richmond, VA
      No offer
      Negative experience
      Easy interview

      Application

      I applied through a recruiter. The process took 1 day. I interviewed at Capital One (Richmond, VA) in Aug 2017

      Interview

      TL;DR: Great people, nice campus, looks promising, but high-caliber engineers need not waste their time until the case interview is revised / eliminated. There were three rounds of interviews. Each one was 45 minutes. The first was a generic technical one (leetcode easy - medium, much more on the easy side). I finished this in 15 minutes. The second was their case interview (more on this later). The third was a generic behavioral interview that was on the casual side so far as these go. Almost everyone I met was very friendly. They give you a tour of the campus before the interview. The one downside of this interview was the case interview. I was interviewed by an older lady and mid-level software engineer. The older lady said that she was the head of the case interview department. They handed me a printed piece of paper with a fake bash shell and asked me some questions about how to build a system that handled data securely given this. The question was open-ended, but it seemed like the lady in particular had a set of items that she was trying to ensure that each candidate identified and solved. The mid-level software engineer barely made eye contact throughout the interview, seeming much more interested in his phone. I built a working solution to the problem (identical to that built by engineers who received offers), but the lady seemed dissatisfied with the way I had arrived at it. The parting interaction was as follows: Lady: “So, do you have any more interviews today?” Me: “One more” [Lady smiles sadly at the engineer, who chuckles, and they both leave the room with that] I interviewed at a big 5 tech company shortly afterwards and accepted an offer there. I was promoted within the first year with significant comp increase in addition to stock rewards / bonuses. Caution is advised to high-caliber engineers applying for positions at this company. It will likely turn out to be a waste of your time, particularly given the significantly higher comp packages at competitive tech / financial services companies.

      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.

      Difficult interview

      Application

      I interviewed at Capital One

      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.

      Design a rate limiter using a token bucket algorithm and discuss how it would handle bursty traffic and distributed deployments.
