I applied through college or university. The process took 2 weeks. I interviewed at Siemens in Nov 2012
Interview
Two to three week process managed by on-campus recruitment. One single interview with two program managers. Managers were very friendly and made the interview process personal and down-to-earth. Heard back about two weeks afterward with internship offer.
