Overall a smooth experience. Recruiter contacted me and then sent an OA, which I wouldn't rate as easy. Try to get at least 3 out of 4 questions right and you will pass. Next came the "Power day" which is basically the virtual onsite consisting of 4 rounds.
There was system design, case, coding and behavioral. Coding is a cakewalk if you have been practicing for other bigger companies. System design was a good experience, my interviewer touched almost every aspect of the design in depth. You can choose to go in whichever direction your forte is like DB, High level, low level, network etc. Question was similar to what you find in other posts.
Case interview was very open ended and some people might find it weird because you cant really prep for it. They also give you a code snippet to debug and some basic quant analysis type of question.
Behavioral was based on standard format of STAR based on past experiences.

LC tagged questions and system design was among the ones mentioned in the other posts.
Ho sostenuto un colloquio presso Capital One (Boston, MA)

Power day style interview, two coding, one system design, one behavioral. Everyone was nice, but the interviewers seemed a little under prepared and/or new to interviewing in general. Questions where essentially leetcode medium/hard almost word for word.

Code assessment then to power day interview with 4 rounds. Overall the power day interviews were okay except for the case study. The interviewer was disengage while being on their phone the whole time. There was a part where the interviewer said fix the mistakes then went back to their phone. I pointed out their code has other errors with template and was ignored. Then while attempting to fix those (10 mins later) they mentioned to ignore that part and focus on the very bottom part of the code. What a waste of time and very unprofessional. This makes me wager a few of the interviewers probably could not pass their own interview process today.

Code signal 4 questions. Power day is one coding question, system design, case study and behavioral.
Ho presentato la mia candidatura tramite un'altra fonte. La procedura ha richiesto 2 mesi. Ho sostenuto un colloquio presso Capital One (Ciudad de Mexico) nel mese di mag 2026

Excelente code challenge después de eso, preparaciones para un powerday q es básicamente 4 entrevistas técnicas en un solo día, es de 1 hora cada uno y al final de dicen si queda o no
