Have interview on Thurs. with Agency, will be taking tests

I have an interview with a nursing agency on Thursday. I am only interested in doing behavioral health assignments, as that is my only experience. I was told that interview would be about 1 1/2 hrs. and that includes filling out application and taking tests. Can anyone give me a clue as to what type of tests? I am just reviewing general nursing material from Nclex book and some pharmacology.
