I applied through a recruiter. The process took 2 days. I interviewed at Siemens (State College, PA) in Sept 2015
Interview
Went to career fair, talked to multiple recruiters, got an interview set up for the next day. It was odd because I was really friendly with one recruiter who was already asking where I would like to be placed, then a second recruiter rudely interrupted and decided he wanted to interview me for his location.
