      I applied online. I interviewed at Capital One

      Interview

      Capital One recruiter has a tendency to ghost on potential candidates if they are not interested. At first, the recruiter calls you and asks you to take a coding challenge. Two coding challenges are presented through HackerRank. Also, the recruiter/HR is very helpful on how the interview will be if they are interested in you. They have a guideline on what to expect. Due to the Covid-19 Situation, the final interview is completed on a Zoom Video Conference application rather than onsite. Four interviews that consists of two technical tests, behavorial, and a case interview. All four interviews are 45 minutes long. Due to employees working from home, one interviewer made the interview a little bit difficult to concentrate, listening to a screaming kid from the background. One technical interview has leet code questions and the other technical question is supposed to be a white board question. But due to the interview not being onsite, the interview was more about my resume/technical background. Behavorial interviewer asks 3 questions. Interviewer expects about 12 - 15 minute length answers using the STAR format. Most were easy to talk to except one who seemed agitated. Overall, they were nice, but deceptive.

      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.
