Pros
There are a wide variety of businesses to tranfer between when your current position is getting stale or cut. DuPont had a tendency to promote from within, so you could start out as an engineer or chemist and end your career in legal, HR, R&D, management, operations, or sales and marketing. This has only gradually begun to change such that DuPont is starting to hire externally for transferable skills such at IT.
Cons
No matter what division, management is highly politically correct, to the point where quality of management has suffered greatly. Many fine and talented employees are passed over for promotions in order to meet an established quota that management is graded and rewarded for meeting. It sounds good in social theory, but the consequences are simply horrific. Nimrods run organizations where it is intuitively obvious they are way over their heads. It's only the talent beneath them that keeps the ship afloat and lurching forward.
