Pros
The opportunity to work with some of the brightest people in the field. Workers are very passionate and motivated.
Cons
Make the right alliances because the company management structure is a continuing game of politics. Some divisions are going through a reorganization. Not to mention, employees will experience a cutthroat environment if your division or program lacks gender diversity. Many meetings are over the phone. Management is spread out all over the country. So if you work in San Francisco, you boss can be in Research Triangle, NC. This adds a layer of complexity in management. Also, you are referred to by your level of education. This is very deterrent when you are not recognized with the work and commitment you have put in. Mid-level employees will be treated very poorly and you will put in more hours than you report (report 40-50 and actually working 60-70).
