The process took 2 weeks. I interviewed at Capital One (Fairfax, VA) in Mar 2021
Interview
Online Coding Test then four round powerday
Case Study and Debugging
Architecture and System Design
Behavioral
LeetCode Algorithms
Felt pretty well about everything apart from the algorithm problems as I didn’t run any code in the hankerrank coding pair. It also couldn’t use my preference of language as it wasn’t supported. It could have easily been solved with regex but you can’t look anything up. Also a very bad interviewer for that round, they were silent the entire time and not interactive. Didn’t seem like they wanted to be there. You have to be lucky on the interviewers.
It’s also very exhausting. Please change it to be split over days. Not everyone can take the time out of work for 4-5 hours of straight interviews
Interview questions [6]
Question 1
Design an application that handles smart meter readings for an apartment building, with the users being tenants and managers
Surprisingly manageable — the interview felt more like a conversation than an interrogation. It began with a sequence of coding questions, including one on merging overlapping intervals. The real challenge came during system design, where I had to outline a URL shortener service that could scale impressively. Interestingly, I had just looked at a similar architecture on PracHub, which helped me articulate my thoughts clearly. The technical questions wrapped up with validating a binary search tree, and I ended with a positive vibe. I received an offer, but ultimately chose to decline it.

Question 1
Merge overlapping intervals from a list of time ranges
Interviewed for an engineer position, the interview was a joke. Asked basic OOP question with a few follow ups - no system design portion. Interviewer was very laid back and chill, didn't take it to seriously.
Was not too difficult. three total interviews all on the same day back to back. technical one, behavioral one and a case which was more of just a debugging question
