I have been working at Marquette University part-time (More than a year)
Great place for research if you are interested on Math, Statistics and Computer Science
Its in the downtown of Milwaukee.
I applied online. I interviewed at Marquette University.
For the interview process, it was a discussion with several different professors about Marquette and course work. In addition, upon applying to graduate school you are automatically considered for finical aid. The position covers tuition and provides a stipend. After discussion with the professors you can increase your odds of a position.
