Canonical's interview is broken into phases. Phase 1 - Application Review I applied to Canonical in Feb, 2023. Phase 2 - The Assessment (Round 1) 1 day after applying I received an online coding test. It was fairly easy. (Round 2) 1 day after completing the test I received a generalized aptitude test. Like an IQ test. Rotate objects in your mind. Find the odd word out. Pick the most distant number. It's "easy" because any human can do it but you are graded on accuracy and speed. (Round 3) 1 day after completing the aptitude test I received a short form free response section with 19 prompts. I wrote 5 pages of text. They gave me a few weeks to complete it. It took me about 4 hours to complete everything. They wanted to know about my high school, college, and professional experience. 3 business days after completing the written test I moved into the next round where there would be human interviewers. I was asked for my availabilities over the next 2 weeks. Phase 3 - Early Stage 1-3 days after giving my availabilities interviews were scheduled. I was not informed. You must check your candidate page yourself otherwise you will miss your interviews. Over the next 2 weeks I had 2 interviews. (Round 4) The first interview was with the tech lead of the team I was applying for. They wanted to know what I've worked on and asked me some domain specific questions about the role. The questions were pretty in depth. There was no coding. (Round 4 pt 2) The second interview was with manager. It was very technical and you really need to know your Linux. There was no coding. (Round 5) 1 day after the second interview I got a take home coding challenge. It took me 5 hours and I submitted it the next day. It was very applicable to the real world and not just a leetcode. Phase 4 (Round 6) 3 days after submitting the code I was invited to take an online behavioral assessment. It was a multiple choice quiz and took 10 minutes. I was also invited to give my availabilities for a Talent Team/HR interview. Their closest availability was a week out. At this point I accepted an offer at another company. There are 2 or 3 more rounds after this point. This is by far the most unempathetic interview process I have ever done. There is no respect for the interviewee's time. The company says that their process is unbiased. I disagree. This process is unfair to people who cannot afford to do multiple take home quizzes, coding challenges, and behavioral assessments.
