I applied online. I interviewed at Canonical in Dec 2025
Interview
Terrible. Long written school-like interview questions, inane cognitive skills test and programming, only to be told I never completed any of them and am no longer being considered for the role. No one replies to my emails, strikes me as extremely poorly managed and shady.
Interview questions [1]
Question 1
How many unique products are there of an array of numbers if you remove each element one-by-one with replacement?
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.
