El proceso tomó 2 semanas. Acudí a una entrevista en Capital One (Fairfax, VA) en mar 2021
Entrevista
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
Preguntas de entrevista [6]
Pregunta 1
Design an application that handles smart meter readings for an apartment building, with the users being tenants and managers
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.
