I applied online. The process took 4 weeks. I interviewed at Capital One in Oct 2025
Interview
This was for the TDP: Online assessment/Virtual job tryout, email questionnaire, then powerday. Powerday consisted of a case interview, behavorial interview, and technical interview. Overall was not too difficult, but being thorough was important.
Interview questions [1]
Question 1
Please name a time you worked on a time, and what you learned from it.
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.
