Pros
DuPont has been great for early career experiences. It allows you to go beyond your core training and advance into other fields if you desire. DuPont also allows for a flexible work environment with good benefits. Great if you get involved in programs like Field Engineering Program or Marketing Leadership Development Program (MLDP). Very diverse businesses (Ag, Electronics, Paint, Construction, Safety, Fibers) and the company has a strong global reach.
Cons
If you are looking to advance quickly, DuPont has its limits. Also they do a poor job in career management beyond the first few years. The company has a very old workforce which can be challenging for new employees. Finally any advanced degrees earned while working at DuPont is not recognized as a benefit to the company unless you leave the company and come back into a different business.
