Pros
Amgen is certainly still one of the best places to work in the biotech/pharma industry. The campus is beautiful, there are plenty of amenities and resources (including an amazing gym, car wash, dry cleaning, cafes, etc), and the surrounding area is ideal for families and those who prefer a relaxed and quiet environment. The product portfolio is healthy and the pipeline is very strong, positioning Amgen well for continued growth and success. In general, the company culture is friendly and positive, although it has become more competitive and stiff over the years.
Cons
Amgen faces organizational challenges common to many large companies. Decision making can be slow, compounded by the many layers of management, committees, and approval processes in place.
