There was hardly an interview process--I was recruited as an intern, then switched over to a full-time staff position.
The whole interview/hiring process took roughly a month and a half. The company moves at a glacial pace and doesn't care if you have impending deadlines (i.e., schools pressuring you to get authorization and proof of internship for class credit).
The questions they asked didn't really pertain to the job--I mostly ended up running the mail, grabbing morning coffee, making copies of meeting presentations. It was all very non-educational but at least I got paid $10/hr.
