Pros
Great opportunities to move internally every 3-5 years. International positions available although getting harder to land. Interesting product that has a global impact on humanity. Generally high standards for safety and ethics. Competitive compensation, stable company although there have been some layoffs in the past 5 years. A true multi-national corporation with many interesting challenges and opportunities.
Cons
With size comes some inefficiencies due to competing internal priorities, difficulty of communication, globally spread groups, etc. Majority of locations are not very 'sexy', tending to be in smaller cities or rural communities (may be a plus, depending on your preference). Culture and mindset tend to reflect the locations. Size, competition, and internal turnover make it difficult to foster a 'family' atmosphere.
