      DevOps Engineer I Interview

      15 Dec 2021
      Anonymous employee
      San Diego, CA
      Accepted offer
      Positive experience
      Difficult interview

      Application

      I applied online. The process took 2 weeks. I interviewed at Illumina (San Diego, CA) in Dec 2021

      Interview

      Applied online. 3 days later got a call to briefly go over resume and the role. 3 hours later was scheduled video call with "Director of DevOps" to go over details of resume and role. 2 days later was scheduled the final interviews (4 back-to-back video calls of 30 min. each). 1st interview was with a "Staff DevOps Engineer" who asked about my DevOps related experience then asked me to write code using paper/pencil (which I didn't have) or by sharing my text editor (which didn't work) so I suggested entering my answer into the chat. The next interviewer entered the call before I even had a chance to do the problem so I was asked to forward my answer by email afterwards. 2nd interview was with another "Staff DevOps Engineer" who also asked about my DevOps related experience then asked me Linux related questions. 3rd interview was with the "DevOps Manager" who again, asked about my DevOps related experience then asked questions relating to Linux, software release, Git, and Docker containers. This interview was less intense then the two before and went on for an hour since I was allowed to take two breaks. 4th interview was scheduled two hours later since it was with the "Sr. DevOps Manager" in Singapore who asked about my DevOps experience and other questions relating to load balancers, containers, SSL, DNS, and CI/CD. Within 3 days I got a call and was given an offer for the "DevOps Engineer I" position, although I applied for the "DevOps Engineer II" position. There reason for that was because I did have the required years of experience, but it was not all DevOps related. So after negotiating the offer and after another 3 days, I accepted the new offer.
