I was taken to a meeting room where I had waited for quite some time and I could tell that no one was prepared to interview me. I was asked about the most basic Linux commands (how to create a directory, create a file, delete a file, ...etc) for the most part even though the position requires advanced Linux administration knowledge even for a junior (which I was at the time). I was expecting a second more in-depth interview but I got an offer on the spot which felt odd, to be honest.
