Pros
I worked at Regeneron for 10 years. In that time, I gained a lot of financial stability, being there for the rise and the first products; Arcalyst and Eylea. I felt the comraderie of a group of people that were all working our hardest for patients. I cried at patient presentations and danced at our holiday parties. Access to the CEOs was very cool. Free coffee and employee 'thank you' money employees gave each other made me feel valued. The company had amazing values like 'you will be challenged every day' and 'we won't let bureaucracy get in the way of great ideas'. I'm sure the Science is still great.
Cons
I had 9 managers in 10 years. Hiring is extremely top-heavy; there isn't much promotion from within and frankly, way too many directors whose only jobs are checking timecards, making strategy for your workflow and sitting silently in your meetings. As mentioned several times in reviews, the promotion process is 100% opaque. Every year you will take on new projects, but only get a 'performance based' salary bump. The company culture has gone from expect to work your butt off but you'll see what you did directly reflected in the bottom line, to work your butt off and here are 15 more trainings on Microaggressions and Compliance. HR is untrustworthy and doesn't respect employees personal space... particularly mental. There's no coming in, doing your job and going home. They tell you what to think on every social issue via their 'internal twitter' account RON (regn intranet), and certainly believe their job is to set the 'moral tone'. Over the pandemic the CSO said 'All Lives Matter' at a local graduation ceremony speech and was castigated over it and forced to make a company wide apology by the woke ladies in corporate compliance and HR. That's how the DEI department was born. Now when you interview, a 'diversity' candidate is presented to the hiring manager from a special employment agency as an alternative to you, so be aware that most will have an extra layer of competition.
