I actually interviewed there last year as I was in the neighborhood, and I liked dSeton Hall's colors and website and got curious. The residents seemed very cohesive, the attendings seemed supportive, and the program director is working very hard to develop this program, though it's only 3 years old now. It's relatively close to NY city, but I got the impression the residents all worked way too hard to have much opportunity to go there, though they seemed happy.
I think the training would be good because you are really "in the trenches" there in Elizabeth, and they seem to see it all. They were in the process of piecemeal remodeling their inpatient psych building, but it still had that upper NJ run down urban feel to it.
I got the feeling that it was not very competitive because it's new and the location. I was all but offered a prematch on the spot.
They seemed to be understaffed with nurses and support staff also, which is a concern.
