I applied through an employee referral. The process took 5 days. I interviewed at Sanofi (Bridgewater, NJ) in Aug 2014
Interview
Telephone interview followed by an in person on-site interview. The telephone interview was with a panel of people. The onsite interview was 4 hours and I met with several people that I would be working with.
Speak to HR about role, then 30 minute video interview with hiring manager about role. Very straightforward - there were no tricky questions, but to be honest - the interviewer did not quite elaborate on the position or the culture of the company. I asked a lot of questions, and I seemed confident on the questions she asked me so I'm not sure specifically on what she wanted. You just get lucky if you get selected to the next round.
