Pros
DuPont is a dynamic, well-established company that definitely offers challenging opportunities for those who are willing to step up to the plate and take them. DuPont employs some incredibly talented people -- especially in R&D -- and seems to be committed to "going where the growth is." In other words, the company seems to be committed to adapting to a changing global economy. The company also recognizes the need for work/life balance and offers flexibility in that regard.
Cons
In my function, there seems to be an old-school attitude that one is hired for life. Very little differentiation (at least in my function) between those who consistently work hard/contribute and those who do not. The company's great attitude about work/life balance is sometimes taken advantage of, apparently without much consequence.
