I applied online. The process took 4 weeks. I interviewed at Canonical (Taipei) in Jun 2022
Interview
After I submitted the application in their website, they sent me a series questions and ask me to compose a essay to answer it.
They said they expect you to spend 1-2 hours to finish it. While the most questions are quite general, like who's the competitors of Canonical? and how you think Canonical can win? something like that. And some questions are about how you were doing in College or High school. I am not a native speaker, so it took me much more time to finish it.
Then they sent you a Aptitude test. I don't think it's like a intelligent test, it's more like testing your speed of some specific kind of questions. Finally, I got their reject letter. I never encountered this kind of interview that interviewer turn you down without asking any technical question.
Interview questions [1]
Question 1
Are you involved in open source software?
Describe any significant contributions to open source (with links where possible), if any
What do you think are the key ingredients of a successful open source project?
Why do you most want to work for Canonical?
Which other companies are building the sort of products you would like to work on?
Which companies have the most interesting approach to devops and site reliability engineering?
What do you think could raise the bar for site reliability engineering, globally?
What do you think Canonical needs to improve in its engineering and products?
Who do you think are key competitors to Canonical? How do you think Canonical should plan to win that race?
It's an extremely long process that includes standardized tests, take home assignments, and several rounds of interviews. It was at least 5 rounds long and you interview across different teams.
I applied through other source. I interviewed at Canonical (London, England)
Interview
They have a really long, tiring interview process. The first round was a written interview where I had to answer like 15 questions. Then a coding interview with 1 hour time that I could do anytime for 2 weeks. Then I had to take a personality test and they totally ghosted me.
The first round is a bunch of questions like 30 or so where you have to describe your expierence, personal and academical information. Then there is a asynch technical interview and a psychology test.
