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.
Average interview
Application
I interviewed at Canonical
Interview
Long and exhausting with sum of 14 stages. Nice technical but some „soft skills” interviews were quite aggressive. In my opinion they do not want to hire true professionals but desperates instead.
Interview questions [1]
Question 1
1. Written interview (>20 pages, you can find questions on reddit)
2. IQ test
3. Coding test (3 random real-life exercises on DevSkiller - the time is tight here)
4. Real person interviews (multiple technical, HR, Hiring manager even with CTO)
5. Month waiting….
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.
