I've gone through it too. Twice. The 2nd time I just told them that their process sucks and they said basically "thank you for applying please don't hesitate to try again!"
I didn't even proceed when I saw what they wanted. I thought about how many people are likely to be applying to Canonical, and decided not at all worth the time.
I pretty much refuse to work at any company that has anything resembling an IQ test.
I once found myself unexpectedly being asked to take a wonderlic test, I failed the math portion on purpose then when I went into the actual interview I said roughly "haha, that math section was so hard".
My degree is in CS & Math, I just didn't want to burn the recruiter relationship.
I mean they probably filter for the kind of people that can tolerate and go through this stuff because their positions are also requiring brainless man-machines
