I applied online. The process took 1 day. I interviewed at Sanofi (Swiftwater, PA) in Dec 2014
Interview
There is a panel. They review your resume experience and then go through a list of HR questions. Be prepared to support what you have on your resume. Also, be prepared with a number of questions to ask the panel in return. Overall, not a very difficult process if you are prepared. Be able to talk about skill listed in job description.
