Pros
Diverse workforce, operating in over 150 countries, providing vast opportunities for career mobility and specialty niche changes, if desired. Very low employee turn-over with a high number of personnel staying decades and ultimately retiring from the company. Committed to high ethical standards, strong privacy policies/procedures, and extremely fair employment practices. It just feels good to know they actually mean it when they claim it.
Cons
Like most (very) large organizations, they have many operational silos and could benefit from taking (and implementing) feedback from employee surveys aimed at sharing operational efficiency and modernization.
