      Senior Software Engineer Interview

      2 Oct 2024
      Anonymous interview candidate
      No offer
      Neutral experience
      Average interview

      Application

      I applied online. The process took 10 months. I interviewed at Canonical in Jan 2024

      Interview

      It was not an hiring process, it was a social experiment. The whole process took 10 months, and (if I did not lose the counts) 11 interviews until a very strange conversation with the CEO which was more interested to know how was my life when I was a teenager. Besides that I knew very nice people on the interview rounds which made me to think, hey it would be good to work at that company, I discussed the salary range with HR and they pre-offered a wage lower than my previous employer. The end of story, after spending 10 months on this, they ghosted and I really don't have any hope to receive an offer. My advice here, if you would like to work for Canonical, make sure that is not the only thing you want, invest effort on the hiring process but have something else, don't apply for positions if you are in a hurry to get employed. Just to give an idea of how absurd this process was, in 10 months I left my previous employer, worked as a contractor for a company, got other 2 offers, and the contract company hired me as a full time employee right after the CEO interview from Canonical, if I had to wait something from this process, I would probably end up with a wasted year. So invest time on this process, only if you would like to participate to this social experiment and if you loose your job in a meantime, or simply don't put effort here, there are plenty of other companies outside there offering good jobs with higher paychecks.

      Average interview

      Application

      I applied through a staffing agency. I interviewed at Canonical in Jan 2026

      Interview

      I understand they are looking for a very specific type of profile. It's just not for me and after a long form with 30+ questions, some of then about my teenage years hobbies or my grades in school, and a intelligence tests consisting on sesame street knowledge like "Peter is taller than Jenny. Who is shorter?" i just withdraw, if that is the respect they have for candidate time i am not a good fit for their culture.

      I interviewed at Canonical

      Interview

      Long process, took a lot of time to complete so-called "written interview", talking about your academic performance during high school and college, which is hated by most people. Interviewers are kind, however, it sucks when the interview process takes you 40+ days to get a rejection email.

      Easy interview

      Application

      I interviewed at Canonical (Adelaide)

      Interview

      It was lengthy. There is the well-known written interview, followed by a basic programming test. Lots and lots of Google Meet interviews. Many of the interviewers asked the same questions. A panel interview would have been a lot better.

      They ask a lot about high school times.
