Vantaggi
There are some really great, innovative people working there; people willing to help and "hear" employees -at all levels. Being around these types of employees can make working here a good expereince -for a time. Having a good manager of course also helps.
Svantaggi
Like any employer, some not so great people; it seems long-time employees are eventually promoted to management level, unfortunately there seemed to be many examples of managers not suited for the management role due to behavior not consistent with management or simply were not effective in the manager role. While an international company, the USA management group seems to be purely domestic in its focus. That just doesn't seem consistent with the company culture as a whole.
