Canonical has an incredibly convoluted, daunting hiring process. What’s seen in the screenshot can’t even realistically be considered the tip of the iceberg. Besides fussing over your high school performance (if you don’t claim to be top X% of your class it’s an instant rejection), they also make you do written quizzes and some “psychometric assessment” (pseudo-science BS). After that it’ll be roughly TEN rounds of interviews, the final one being with Mark Shuttleworth himself who may very well be a dick and decide he simply doesn’t like you.

If you’re curious, someone has written down their full experience here: https://www.dustri.org/b/my-experience-with-canonicals-interview-process.html

I once considered applying to them since they have a lot of interesting job postings on LinkedIn, but after reading through these experiences I decided this simply wasn’t worth it.

I skip anyone that requests it, it‘s not a good sign to me. It‘s them screening undesirables.
