I applied through college or university. I interviewed at Capital One in Nov 2019
Interview
For internship/recent grad, the process involved a phone call followed by a 3hr session consisting of technical interview, case study, and a behavioral interview.
The technical interview has a design problem and an algorithm problem with multiple parts. Case study incorporates pseudo-coding and thinking of edge cases around a business problem.

Question 1
Justify using one data structure over the other for this problem.
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.
