      Software Engineer Interview

      Oct 18, 2022
      Anonymous Interview Candidate
      Saint Louis, MO
      No offer
      Negative experience
      Difficult interview

      Application

      I applied online. The process took 6 weeks. I interviewed at Capital One (Saint Louis, MO) in Oct 2022

      Interview

      The first half of the interview process consisted of a recruiter reaching out to do a phone screening and getting you set up with the technical assessment. The technical assessment was average, not terribly difficult. The second half of the interview is a "Power Day" where you do four interviews in four hours. These interviews consist of a behavioral, a case, and two technical. These interviews are a bit tough, but they are doable as long as you are moderately experienced. The part that was the most frustrating throughout this interview process was that the recruiter who was facilitating everything for me was extremely unprofessional. He was a day late for our scheduled phone screening, consistently missed scheduled phone calls, and even accidentally scheduled my interview for the wrong day. It took me two weeks and missing three scheduled calls to get feedback from him. Overall, the interview process took six weeks.

      This took a bit longer than expected, stretching over several weeks. The technical rounds were intense, featuring an LRU cache implementation and a problem on detecting duplicate transactions within a 60-second window. I was nervous at first, but it clicked for me when I realized I had practiced a similar approach on PracHub just days before. Unfortunately, I didn’t receive an offer in the end, but the experience was a solid learning opportunity. The behavioral questions felt straightforward, so I wish I had made a stronger impression in the technical segments.
