I applied through a recruiter. The process took 1 day. I interviewed at Amgen (Thousand Oaks, CA) in Jan 2016
Interview
First round interview was on campus. They brought all the interns in for a superday interview process. There was a panel behavioral interview followed by a fairly straightforward case involving a recommendation for a manufacturing operations situation. All in all a pretty straightforward interview process and they take good care of you throughout.
