The process is supposed to be 5 steps. They seem to involve a lot of people you won't necessarily interact with in the role. In some interviews I was asked if I had already had an interview with X person so it does seem like they don't coordinate the steps well. They seem to ask a lot of definitions versus how to prove you can work in the software which I found odd. They have an ancient way of doing things from my perspective. Seemed like they wanted someone who could spit out definitions and answer every question to the book. They do want someone who is proficient in Linux because that is how they process everything.. It is an average interview to someone who knows linux but can be difficult to someone who is used to using enterprise software to resolve issues and not linux.
