Canonical has no regard or respect for applicants' time as their interview process is ridiculously long and some parts were just weird and insulting. The interview process consisted of (in order): a 50 question response essay, a python coding test (multiple choice + 2 long answer), an IQ test, three technical interviews, a behavioral test, interview with hiring lead (I made it up to here), and an interview with management. Overall, the interview process left me feeling degraded, humiliated and was a complete waste of time. I was disqualified at the very end of the interview process because I lacked enough experience with Linux, even though I was clear and transparent about my experience level from the initial application. To make me jump through all those levels of interviews, write an IQ test, write an essay response to 50 interview questions all to lead to being disqualified over something that should have been picked up on from the initial application screening was incredibly unprofessional and a huge waste of my time and the company's resources. The only good thing in my experience were the three engineers that interviewed me in the technical interviews, they were friendly and professional. I strongly implore you to stay away from this company.

Spent few days during my free time to answers 45 pre screen questions. The time frame was to submit in 2 weeks. Submitted hoping a good answer. Got reply in few hours when i submitted on 10th day that i was rejected. No reason given for rejection.
