      Linux Kernel Engineer Interview

      17 Nov 2023
      Anonymous interview candidate
      No offer
      Negative experience
      Difficult interview

      Application

      I applied online. The process took 5 weeks. I interviewed at Canonical in Aug 2023

      Interview

      Before you may speak with a human beyond the usual recruiter emails you must complete a lengthy personal essay and standardized test. If you clear these steps you move to what seemed like a more traditional interview process, albeit extremely lengthy yet again. Luckily I didn't make it past the standardized test because I don't have enough experience. As for why they couldn't have just read my cover letter or resume and made that determination without the term paper and standardized test? I haven't a clue. The process was disrespectful of my time and as a huge FOSS enthusiast they have lost my respect entirely.

      Negative experience
      Difficult interview

      Application

      I interviewed at Canonical

      Interview

      Terrible, extremely inconsiderate of candidates' time. Included 3 interviews, IQ type test, extended questionnaire before getting declined with potentially more steps if I had continued. I would not recommend wasting your time.

      Question 1

      What is the difference between Apache and OpenGL licensing?

      I applied online. The process took 2 months. I interviewed at Canonical (Calgary, AB) in Sept 2024

      Interview

      There are several stages in the interview process: (1) A long written interview (25-35 long answer questions). Be prepared to write 10+ pages in response. (2) An aptitude test. (3) An long take-home technical test. Probably 6+ hours of work. (4) "Early stage" interviews with a variety of employees, including your hiring lead. (5) Meeting with a member of the "Talent Team" (not sure about this, I didn't make it this far). (6) "Late stage" interviews.

      Interview questions [1]

      What are the different locking mechanisms in the Linux kernel, and what are some advantages/disadvantages of each method?
