I applied through college or university. The process took 6 months. I interviewed at Regeneron (Tarrytown, NY) in Jan 2019
Interview
Found out about Regeneron via an HR colleague that visited my graduate school. I applied via the school site (several years back). Enjoyed the interview, had interview with 5 members of the team, one on one.
Video recording. Answer questions they have and record your answer. Questions were general questions. Tell me about yourself. Why do you want to work at Regeneron. What do you want to gain out of the internship?
