I applied through an employee referral. The process took 3 months. I interviewed at Regeneron
Interview
Applied online and was referred internally. Long interview process including two rounds of interviews to meet with a total of 15 people 1:1. Most of the interviews were repetitive and just went over my background. Also used STAR format questions.

Question 1
No really difficult questions, just conversation about background, strengths and weaknesses. Was asked to give a presentation without any direction.
