      Senior Software Engineer Interview

      26 Aug 2022
      Anonymous employee
      Accepted offer
      Neutral experience
      Average interview

      Application

      I applied online. The process took 5 weeks. I interviewed at Capital One in Aug 2022

      Interview

      I applied for a frontend position online. Contacted by a recruiter within 2 days for a phone screen. 70 minute online assessment (CodeSignal) with 4 questions (2 easy, 1 medium, 1 hard). Some simple array navigation, a 2d array / nested loop, and an undirected weighted graph question I couldn't figure out. Seems like you just need to get 50%. "Power Day" was 4 back to back interviews via Zoom. First tech interview was an easy CodeSignal prompt on forms in my JS framework of choice, talked about some JavaScript syntax and performance. Second tech interview was a frontend design prompt to build a SPA. Questions around component structure, routing, data flow, Redux, API calls, and more in depth knowledge of frontend frameworks. Behavioral interview, pretty straightforward STAR questsions. The interviewer didn't seem to like my answers. Not sure if he thought I made up the scenarios I provided, but he gave me push back on most things I said. Seems like they just want to get more out of you to write down for feedback. Case interview walked through a business case for calculating costs. First, think of requirements and considerations. Second, talk through some example calculations and a formula. Finally, I had to identify and fix the algorithm in a faulty code sample (no formal testing, just talking through it). Most interviewers were friendly and had good things to say about the company. Was rejected for the original position I applied for, but was contacted a week after my interviews to meet with hiring manager for a different team.

      Application

      I interviewed at Capital One (Boston, MA)

      Interview

      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.

      Interview questions [1]

      Question 1

      Leetcode Count primes, looking for optimal solution

      Application

      I interviewed at Capital One

      Interview

      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.

      Interview questions [1]

      Question 1

      Code signal 4 questions. Power day is one coding question, system design, case study and behavioral.
