Pros
Location.... Time off work. Big company in a small community. At times it still has that small company excitement. The benifits are not bad for a self insured company. But they have slipped in recent years.
Cons
Lack of Leadership. Its really a old boys club.. There seems to be blinders on the Management at the top. There seems to be a lack of knowledge with management. they seems to be very arrogant yet have no experience in either there field of work or their ability to manage people. Amgen has allot of people who are GREAT individual contributors but severely lack the ability to manage people. Amgen is very much a good old boys club or popularity contest. If your like then you move up of not then oh well. Amgen also has been know for moving managers around, so when it comes time for reviews you may not be reviewed by a person who has seen your performance. You can have 2 or 3 different managers in a year
