Huge time sink, they won't tell you why they reject you. Went through an essay, a bunch of tests, and a really unresponsive recruiter. Honestly, not even worth trying to apply unless they fix up their process.
Interview questions [1]
Question 1
A whole bunch of high school questions, then some weird questions comparing their development practices to other companies.
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.
