I applied through an employee referral. The process took 1 day. I interviewed at Regeneron (New York, NY) in May 2021
Interview
Interview was approximately 6 hours of back-to-back 1:1 conversations with managers and members in the group I was applying to. Never interviewed that way before, and it was a good experience. It allowed me (a prospective candidate) the chance to get to know the group I would be working with and for them to get to know me.
