I applied through a staffing agency. I interviewed at Capital One in Mar 2020
Interview
4 rounds with total including initial phone call about the opportunity. Second and third rounds with the team, and the final round with the hiring manager and the lead. Except the first round, the other rounds were about an hour. Pretty much about the technologies experience in the job description and on my resume. Plus some coding.

Question 1
I was given small piece of code, and asked to explain what it does, and what would be the results of given input examples.
4 rounds of interview including coding , design , case study, behavioral after clearing the code signal assesment. Coding was medium hard of 2 questions each. case study and system design was difficult.
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.
