Canonical Junior, Software Engineer interview questions

The interview was very rushed, and I could tell they had made their decision before even interviewing me. The interviewer was incredibly rude and I could tell that he clearly didn't want to be there.

Did an initial screening call at 8pm one evening which went well enough. Was then sent a take-home test which I completed successfully in a few hours. The next day I received a no-reply email which a rejection. I found the lack of feedback or personal email to be quite rude considering the time I had put in.
