Apply online @ www.umjobs.org. If you have not taken their "tests" which include: written, logic, basic math test, then HR will require you to do so before applying. Once applied and if they call, they usually request a phone interview before in person.

In person. Questions were behavioral based and scenarios with CER answers. Pretty standard interview, almost scripted. Pretty easy to nail just be "pro-blue" and act like you really want to be there. Also, helps if you want to further your education and act interested in advancing.
