Pros
Good pay, raises and stock. That's about all I can say that is good about this place. If you like money with a price this is a good place for you.
Cons
Honestly stayed for the money and decided to leave because at the end it wasn't worth my health. I can work long hours and offer ideas- that wasn't the problem. The people, management and the overall culture has changed since I was hired four years ago. My boss was mentally abusive and cold as well as belittling and the people around me and outside of my group began looking for ways to hurt people's livelihood instead of work as a team. People would get others fired or demoted with no remorse and this is the new culture of Regeneron. Aside from the entry pay and stock- which is falling daily now I would never recommend this place to anyone I care about. It literally takes over your life and sucks the life out of you.
