I applied through a recruiter. The process took 2 weeks. I interviewed at Regeneron (Sleepy Hollow, NY) in Jan 2017
Interview
Call from a blind recruiter from a schlock-house agency for a very limited "screening". Then a call with an onsite contractor, yes, contractor. This was followed by an onsite visit to shake hands and see the Tarrytown coffee bar. Literally that simple.
