I applied online. The process took 2 days. I interviewed at Merck (Rahway, NJ) in Oct 2011
Interview
Company moves somewhat slowly through the interview process. After an initial phone interview with the hiring manager and team leader, two weeks later an on-site interview was extended.
Aside from accomodations being set quickly by the travel department, most aspects of the 1:1 interview were poorly planned. Didn't receive a schedule for the day until right before dinner the night before. Dinner was with two team leaders. The full interview day began with a research presentation followed by a total of 7 1:1 interviews, which ranged from casual discussion to questions about research. Never heard back with either an offer or rejection. Most people were pleasant to talk to; some were quieter than others and required more leading of the discussion.
