I applied online. The process took 2 weeks. I interviewed at Capital One (McLean, VA) in Mar 2019
Interview
Applied online then contacted by a recruiter after a week, set up a phone interview with a Sr. manager, Software engineer ? I feel like they are just doing the interview for the sake of saying we tried to fill this position with other candidates but probably have someone in the interviewers mind!
Interview questions [1]
Question 1
tell me about your current project, technologies you are using, and talk about restful web service, emerging technologies like docker, aws, kafka... . and Ha, very funny question how many lines of code did you write in your project 😀
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.
