I did not interview in NYC, but I did interview at Northwestern and LOVED it. I do not think that they are malignant at all. I think it is an amazing training program. All the residents seemed very happy and could not stop gushing about the program. Plus, they are building a beautiful new free-standing women's hospital in downtown Chicago. It is HUGE, and will have 30 some LDRs. I think they will be delivering nearly 15,000 babies there a year.
