Pros
I worked for DuPont for 10 years as an engineer. The only thing that I enjoyed about the experience was the people that I worked with on a day to day basis.
Cons
The site management was inept at best. They were cycled through our plant every couple of years to get their tickets punched. I went through 4 layoffs in 10 years. Fortunately I survived them all and was able to leave the company on my terms. But it was always a stressful time that occurred every 2.5 years or so. The morale at my facility was pathetic, early on I thought that it may have been just something at my location. But I had some opportunities to work at other locations and I quickly learned that it was the same at those facilities as well. My advice particularly to new college graduates is if DuPont comes to your university recruiting do yourself a favor and pass them up. I was told once by a 30 plus year DuPont employee that, "DuPont does not hire bad people, it creates them". After having worked for them for ten years unfortunately I would have to say he was right.
