This is is brutal, especially the interview with Shuttleworth:

To the question "How was your university?", I answered that it wasn't prestigious, and pretty small and rural, as we could see cows from the windows. Shuttleworth immediately interrupted me to say "don't play games, don't try to muddle your answers. I'm interviewing you for a senior position, I'm asking you questions, I'm expecting straight answers." I was so flabbergasted that instead of answering properly ("As I'm interviewing for a senior position, I'm expecting proper senior position related questions."), I gave a meek "Okay…" Some parts of the conversation were equally awkward and filled with an unhealthy amount of salt, especially about upstart ("They're a reason why Chromebooks are using it", the reasons are mostly technical debt, not technical excellence.), mir ("Wayland has the same design flaws as Xorg"), … At some point, someone bought him a plate, and he started to eat, without excusing himself about doing so. I asked him why he would spend time interviewing prospective employees in non-executive positions, let alone individual contributors, as this is likely eating a lot of his time, given that Canonical currently has around 1200 employees. He told me that he like to know who is hired, and that this process allows to root out average candidates. After 40 minutes out of a 60 minutes scheduled interview, Shuttleworth said "Ok, nice talking to you, have a nice day," and abruptly ended the interview. I seriously thought about withdrawing my application, as I really didn't want to work with him, but since the position was only senior IC, odds are that I wouldn't have to, so I didn't retract it.
