      Backend Developer Interview

      Jul 15, 2021
      Anonymous interview candidate
      No offer
      Negative experience
      Average interview

      Application

      I applied online. The process took 6 weeks. I interviewed at Cobblestone Energy in Jul 2021

      Interview

      The interview process is 6 stages. This includes 2 online tasks and 4 interviews. It takes 6+ weeks to get through it all due to bad scheduling (1 interviewer is only available Wednesdays, another only Tuesdays etc) The first technical task was a glorified IQ test quizlet, which while very easy, already set the tone for the professionality of the company. After passing that initial screen, they send a PDF ridden with spelling, grammatical and formatting errors, outlining what the next stages of the interview will be. The second technical task was a more legit coding challenge. The first interview with a programmer was cringe inducing as he read the problem statements verbally without writing them down, which was impossible to understand given both his accent and the bad quality of his microphone. The second technical interview with their CTO was better as he was more professional, but at that point I was already about to give up on the interview process. It was after this stage that I was rejected, and I have to say that the emotion felt like what I imagine it feels like to be rejected from a McDonalds.

      Interview questions [2]

      Question 1

      "How would you solve a complicated problem using Postgres" (seriously)
      Answer question

      Question 2

      (In a thick, difficult to understand accent, over a tinny low quality microphone) "you have a table of cars and a table of tires and there is a relationship between cars and tires, how would you select tires without running into a double select issue"
      Answer question
