I applied online. The process took 4 weeks. I interviewed at Capital One (Chicago, IL)
Interview
For the power day interview, it's four rounds, in one day.
The algorithm one I used the heapq in python, and the interviewer was not happy. There is also a debugging interviewr, I thought it was easy, but who knows maybe failed on it.
Interview questions [1]
Question 1
For system design, it's still the old bank design.
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.

Question 1
Leetcode Count primes, looking for optimal solution
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.
