      Data Engineer Interview

      23 Aug 2022
      Anonymous interview candidate
      No offer
      Negative experience
      Difficult interview

      Application

      I applied online. I interviewed at Capital One

      Interview

      First I talked to a screener, then was sent a take home test that has completely made me rethink working for this company. It was a 70 minute timed test that required access to my camera, microphone AND my entire screen to make sure I didn't "cheat" by looking things up like every programmer does dozens of times per day. The questions were mostly mathematic or algorithmic. I'd be very surprised if any of it even slightly resembles a day in the life at Capital One. Without the ability to look up a single thing, I lost a lot of time simply trying to quickly figure it out (the test platform doesn't allow debugging btw so have fun writing out print() statements if you want to monitor execution in any way) or having to work around not being able to look up a simple basic thing. I wasn't able to finish. I'm an experienced senior dev. Overall I'm not even sure I would want to work for Capital One after this. This test showed a willingness to massively invade my privacy and waste my time as well as being completely out of touch with how solving technical programming problems works in 2022. I've worked under enough bosses like that.

      Interview questions [1]

      Question 1

      Calculate arbitrary things such as moving all the vowels in a string to the next vowel in the string, with the last one looping around to the first. Or returning a boolean based on whether or not a given word is a palindrome. You know, the sort of thing devs work on every day.

      Application

      I interviewed at Capital One (McLean, VA)

      Interview

      too technical but covered all grounds, enjoyed the process. It kinda boosted my expectations, which is rare. Was stuck at a point and the hiring manager was kind enough to help me a bit, was nervous but hopefully everything went amazing.
