Pros
Two weeks of paid shutdown per year. Good benefits. Once you've worked here, you are a desired talent at most biotech firms.
Cons
Excessive metrics of every function (analysis paralysis) no longer a nimble organization. Uninspiring management, filled with good old boy politics, promotion of incompetent or mis-casts proteges. Promotions based on who you know, not talent. So many really talented, sharp people have made a mass exodus from the organization due to the politics, poor leadership and inability to move their career forward. The DNA of the company and what it once had as value in the talent pool has evaporated. Most of field sales force are new or less than three years tenure. You'll find a lot of people "hanging on" to keep benefits and retirement options or people that came over for the Amgen they heard of but no longer exist.
