I applied through a recruiter. The process took 6 months. I interviewed at Lutron Electronics (Coopersburg, PA) in Sept 2012
Interview
Very lengthy and in depth interview process, you are interviewed my numerous people (5+) and then each persons scores you as the process continues. If you a strong candidate you may be invited to lunch. The longer the process the greater your chances of getting an offer. Part of interview was role playing a sales scenario and giving presentation.
