Since you have a phone interview, I am assuming you live far away!
I, too, had a whole list pulled up in front of me full of answers to common interview questions. I also had a bunch of questions ready to ask them sitting in front of me too.
Since I was far away, one of the first questions interviewers liked to ask me was, "Why North Dakota?"
After talking to a few interviewers, I've been told that the entire state of North Dakota are short-staffed. They "cannot seem to find enough people with the right skill-sets."
Oh yes, and do sound happy and excited! Make sure to show them you're really interested and be sure to know stuff about their facility!
There's gonna be some challenging questions, but just be truthful.
