      Difficult interview

      Application

      I applied online. I interviewed at Capital One (Santa Clara, CA) in May 2026

      Interview

      Remote coding interview: 60 min long. Prereq: turn on camera, turn off all other browser tabs. 4 questions: 2 easy, 2 medium-difficult. The third one was about converting the variable names from snake case to camel case, without affecting constant names.

      Interview questions [1]

      Question 1

      The third one was about converting the variable names from snake case to camel case, without affecting constant names. That is, you are given a function comment which contain identifiers for constants, variables and functions enclosed in backticks. All of them are in snake case, i.e., alphanumeric segments with underscores in between. The constant names are all in upper case. The task is to convert function/var names alone to camel case, i.e., every new word begins with upper case, no underscores.

      Don't waste time on here. If though you pass the interview, they won't hire you, you need to wait for team matching which make sense at this point, but they will tell after 3 months that they don't have head count. What a nice waste of time.

      They copied what everything Amazon do. Prepare for Amazon interview help a lot.

      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.

      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.
