Lengthy process more than 7 rounds.It takes around 3-6 months to complete the whole process.No guarantee of visa sponsorship at this company.Ask about visa related queries in the beginning stages of interview so it will save your time.

So I know three people, including myself, who interviewed at Canonical for different jobs - we all went through the process at different times. Each of us made it through every interview round and got great feedback from our interviewers - they seemed really impressed with what we knew. But then? All three of us got rejected with some generic auto-reply email that didn’t even explain why. No real feedback, nothing. The funny thing is, we all ended up landing jobs at solid startups and big tech companies, but somehow couldn’t get an offer from Canonical. Honestly, their whole interview process feels like a joke. Sure, you might learn a thing or two while interviewing, but I wouldn’t recommend anyone waste their time with their crappy process.​​​​​​​​​​​​​​​​

Multiple rounds, including technical assessments. There was a written assesment, Thomas international assesment and python assesment with DevSkiller. Interview with actual people come later if you pass all these steps.
