I'm writing this review to hopefully prevent someone from going through the same pain that I experienced with this company. First, as everyone mentions, this was an extremely lengthy interview process, which included 5-6 interviews talking with people, a personality test, an aptitude test, and a presentation. The people were incredibly nice and I was looking forward to working with them after receiving an offer. After agreeing on terms with the hiring manager, I was told they had to rescind the offer because it was a red flag that I asked if it was possible to have more vacation. This seemed strange as they give three weeks but require you to take one when they close over Christmas. They then said that the offer wasn't approved by HR. After an almost 3 month process, this was beyond frustrating, especially because I had turned down another offer at another company that I had limited time to decide on (thinking I was safe since I had already received an official offer from Canonical). I don't like writing negative things about any company however I don't want anyone else to waste their time. There were a few red flags throughout the process (ie: poor or lack of communication) that I wish I had paid attention to. I'm hopeful that you will if they happen to you.

Why you want to work there, all other basic interview questions.
9 interviews before being rejected because my English was not up to the last interviewer standard. Lots of interviews with individual contributors who helped get the vibe. An extensive written préparation is asked, it took me about 10 hours to prepare it

The interview process at Canonical was one of the most extensive I've encountered. It included a written assessment ( about 38 questions), cognitive and personality tests, three early-stage interviews, a talent/HR interview, three final-stage interviews (including a timed presentation and panel exercise), and a final executive conversation. The process stretched across nearly three months, often with long periods of waiting between steps.
While many of the individuals I spoke with were kind and insightful, the lack of communication between stages and the absence of any personalised feedback at the end was disappointing—especially after investing so much time and preparation. After eight hour-long interviews and multiple assessments, I received a rejection email over a week after the final round, with no explanation or guidance.

The negative reviews are legit. This company will waste a lot of your time with different types of assessments as part of their hiring process. I'm still not convinced that anyone actually looked at anything that I did.
