      Devops Engineer Interview

      20 Jul 2018
      Anonymous interview candidate
      No offer
      Negative experience
      Difficult interview

      Application

      I applied online. The process took 3 weeks. I interviewed at Aha!

      Interview

      First interview with a security engineer went OK? A little condescending but ... OK... I get it, security is not a fun field to be in these days. I got the thumbs up to proceed to the next interview, this is when the fun starts. My second interviewer was ~15 mins late... when he finally gets there, interview went well... bumped up to the next round, CTO. This is when it gets really crazy, 3 interviews all going over an hr of the scheduled times, most of them he was late to. Overall, he is a very knowledgable engineer, but wow... The questions were pretty ridiculous for a DevOps Engineer role, he was asking what kind of binary trees are implemented in MySQL, how hash tables work, and other awesome data structure related trivia I hadn't seen since my Comp Sci courses 10+ years ago...what? Who cares? I mean not everyone is a PhD or has the daily/weekly refreshers on this stuff. Somehow he is convinced you need to know this to be an effective DevOps Engineer. Power to them, the vast majority of us out there - please don't waste your time.

      Interview questions [2]

      Question 1

      How do hash tables work?
      Answer question

      Question 2

      What data structures does MySQL implement? i.e. why does indexing help?
      Answer question

      Thanks for the feedback. We do our best to make the interviewing process as candidate-oriented as possible, but we do not always get it right. We have discussed your comments with the interviewing team. I also want to share a bit more info on the DevOps role. It is definitely a unique position. We are looking for someone to implement and automate operational tasks and have deep knowledge of the systems we use (operating systems, databases, application framework) to help the engineering team respond to, understand and troubleshoot production issues. Deep knowledge of how the operating system and database work under the hood helps immensely when architecting the infrastructure, or solving an issue. We use Ruby for both our application code and our automation infrastructure and we expect DevOps engineers to work side-by-side with the rest of the engineering team, following the same processes for their development too.
