Look it up so it isn't just coming from me. It's a quick Google "Canonical hiring process" and there's no shortage of wait wtf was that type of posts on this. You can also go on their website and try to apply for any job just to be further shocked.

They ask for; A massive multi-choice questionaire. A massive free form list of questions. An ask for an essay. Grades from High school through to University. That's to start the process of many rounds of interviews followed by finally an interview with Mark Shuttleworth himself who's known to say no on vibes.

Personally i applied for a senior management role after ~30years working at multiple other very large and well known companies. The pay at canonical was literally 1/5th but i was curious. I was honest about my high school scores and immediately given a thanks for your time but we will pass dialog on their website after stating maths scores in year 9. I'm not even fucking kidding. Obviously i was gobsmacked. It was a blessing to get knocked back that early all things considered.

Not my post but has more detail and matches what i saw. Be amazed at the insanity in the leadership at Canonical that allows for this; https://www.reddit.com/r/recruitinghell/comments/15kj845/can...

We're talking put him in a straightjacket loony tunes type of shit when it comes to Shuttleworth. You can also look up various personal interactions. It's utterly fucking insane.
