      Senior Software Engineer Interview

      Negative experience
      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.

      Interview questions [1]

      Question 1

      Application

      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.

      Find the position of matched bytes in a large data memory

      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.

      Interview questions [1]

      Question 1

      They ask a lot about high school times.
