Fiz uma entrevista na empresa Capital One (McLean, VA).
Entrevista
The process included a few phone interviews, and half day final round interview with 4 engineers and managers. I appreciate that the process is shorter than many other places, but they way they handle candidates is very poor. After I was told that I "passed" the final round interview and was to be matched with a team, I was ghosted by the company. Astonishingly, the same treatment was given to another applicant that I know personally. This is in my opinion highly unprofessional behavior.

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.
