The interview process at WM IT is a model of hierarchy and machismo. They are filling empty chairs, not building teams and teamwork.
Hopefully you will interview with potential peers you will work with, but this is not a given.
You'll definitely interview with a number of managers and directors who may or may not actually understand your job role or ask you relevant questions. They tend to look down on you and be know-it-alls.
Then, if you past their sniff test, you will interview with a panel of IT executives who really should be busy doing something else. This is basically the Inquisition. If your personality or answers don't meet their needs, regardless of what your potential peers think of you, you will be disqualified.
What's so strange about the interview process is that in spite of all the Important People you are judged by, it is flawed considering the outcome in the workforce -- WM's overall IT culture is dysfunctional, distraught and distrustful. it is driven by "me", not "we". It is competitive, not collaborative.
So, good luck with that interview. It proves nothing.
