I applied through an employee referral. The process took 2 months. I interviewed at Regeneron (Rensselaer, NY) in Apr 2018
Interview
I was referred by an alum of my university. There was a normal behavioral interview on the phone within 1-2 weeks of submission of the application. I heard from the company that they wanted an on site interview within a week. It lasted half a day and was very professional. It was a series of 4-5 30 min interviews, first with HR and the rest by managers of the manufacturing team. There were many standard behavior questions, with only 2-3 technical questions, all of which were more for testing how you think about something, rather than the actual technical skills. I received an offer about 3 weeks after my on site interview
V well organised interview process with members of both the manufacturing department and hr department. Everyone was very friendly and put me really at ease- really felt they wanted to hear what I had to say and were genuinely interested
Phone screen followed by a panel interview several weeks later. Panel was 5 or 6 30 minute sessions with 1 or 2 managers of varying levels in the manufacturing department.
First there is a phone call, then 2 interviews, mine were on the same day with an hour break in between. They email you material after the phone call interview, a lot of the questions were based on that information
