      Devops Engineer Interview

      May 23, 2021
      Anonymous Interview Candidate
      London, England
      No offer
      Negative experience
      Easy interview

      Application

      I applied through a recruiter. I interviewed at G-Research (London, England) in Sep 2020

      Interview

      Recruiter found me through a job site. I was mainly interested in the company because I had an interest in moving to London. My first interview was a conversation with the hiring manager to learn about the roles. That was followed by a timed hackerrank test which was fairly easy. After the hackerrank submission was accepted, I interviewed with two members of the team to go where we spent much of the time going over my hackerrank submission. While they were fairly nice, one of the interviewers (the one who did all of the talking) claimed that my Python looked like C++ and that he could tell I had spent many years as a C/C++ developer by looking at my code. I don't believe this is true since I try to write Pythonic code, and, while I've spent many years writing C/C++, I had also written a good amount Python at that point. He then claimed I could have written my code more compactly by using the "max" function to find the maximum length string in a list of strings. This is NOT true. He claimed that the "<" operator returns true if the length of the left operand is shorter than the right operand and that strings. This is NOT true. He claimed that strings are compared from right to left. This is NOT true. Pretty much every programming language performs string comparison by looking at the lexicographic ordering of each character from LEFT to Right. If what the interviewer claimed were true, string sorting would result in a completely unintuitive, non "dictionary" ordering. A week or so later, after not having heard back from the recruiter, I asked for an update and was told they're going with other candidates. The only feedback I got was the thing about my Python code looking like C/C++. Needless to say, it's quite frustrating to have my Python coding criticized by someone who clearly doesn't have a good grasp of Python. But I guess the Dunning Kruger effect also applies in the UK.

      Question 1

      Easy hackerrank problems. I think there three problems.
