I applied through a recruiter. I interviewed at Capital One (McLean, VA) in Oct 2024
Interview
Here's how final round went: 1 round case study where they asked about Virtual Credit Number initiatives and its pros and cons and how it would be implemented. 2nd round coding session where you just need to use dictionary in Python. 3rd round behavior, basic questions (tell me about a time you displayed leadership, etc). using STAR

Question 1
Tell me what you think about a Virtual Credit Number initiatives and its pros and cons and how it would be implemented.
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.
