I applied online. The process took 3 months. I interviewed at Merck (West Point, PA) in Jan 2012
Interview
The interview process was a gauntlet of sorts - I met with 3 different hiring managers at 3 different times. They asked a bunch of questions for 30 minutes, then I switched. It took a LONG time to hear back after applying, but didn't take that long after the interview to get an answer.
