      Site Reliability Engineer (SRE) Interview

      6 Jul 2016
      Anonymous interview candidate
      New York, NY
      No offer
      Neutral experience
      Average interview

      Application

      I applied through an employee referral. The process took 2 weeks. I interviewed at Datadog (New York, NY) in Jun 2016

      Interview

      Recruiter phone call, technical screening, homework assignment, in-person interview, long wait, then they changed their mind and the position wasn't really available in my location after all. The logistics of the in-person interview were impeccable. One meeting was with 2 current junior SREs. The junior employees were not very comfortable running the interview. Another meeting was with a senior guy who ran a very good interview. The last was with the CTO, who ran the best interview of all, really giving a clear idea of what he wanted to know and leaving me room to sell myself as I wished.

      Interview questions [1]

      Question 1

      How would you write a buffered IO layer? When would you use it? What are the drawbacks of using it?
