I didn't make the cut for being interviewed. I come from a long, proven track record of people management . I received continuous, incredible feedback for my interpersonal and team leading skills in the past. I answered the overwhelming amount of weird questions candidly, since I skipped school a lot as a teenager (35 years ago) I could not say that I had stellar math skills at the time, which seems to be ultra super duper important at this company. Having incredible high school grades does not prove that you're a good people manager, developer or person. It will just prove that you were mature as teenager, and that you had a calm and stable family situation to study. One tip to Canonical would be to extend the recruitment process into the probation period (or first time at the company). You are most likely wasting enormous amounts of time and many missing out on great candidates.
