Canonical Software Support Engineer interview questions

I had read the reviews about the interview process and how arduous it could be so I knew what I was getting myself into, but it's definitely not worth the time unless Canonical is your dream company in my opinion. The first stage was a written interview asking several questions like why I'm interested in the company, professional experience, and college experience, and high school scores (i.e., were you a top performer). This was fine since I recently graduated college but it seems that these are standard questions even for those who have been in the industry 10+ years. The next was a psychometric analysis. Four different categories to 'test' cognitive function in various fields, although it has been scientifically proven to be biased and not the best measure (especially those that are neurodivergent). The round was 3 interviews. I was told the first would be a technical Linux OS basics interview. It was as expected, but slightly strayed off what I would consider these topics because they actively were looking at my resume and ask me questions about my experience. The second was another technical which I assumed would be coding. It was not. Many of the questions were the exact same questions I got asked in the first interview. I was told by the second interviewer the third round should contain some sort of coding in Python. The third round was 'Product Engineering'. Right off the bat the interviewer was unprepared. Actively reading my resume and at one point didn't feel like reading it so he told me to tell him verbally what my resume was. He immediately just started asking me questions based off of my experience and he came off as very rude. It seemed he couldn't comprehend why a recent graduate would be applying to this role. He asked, "Do you even know what this role is?" "What do you expect to be doing daily in this position?" "You realize that this is a very technical role that will be very challenging." He also asked about my implementation of a project I had previously done and he had a thick accent so I couldn't fully understand his questions. He got frustrated. The interview ended pretty quickly.
