Ok, probably not the topic post to be using to get on geisinger's bandwagon, but here goes anyway. I interviewed last year and these were the stats we were given: 99th percentile on intraining exam last year as a group (great emphasis on teaching), hundreds more cases by chief year than any other program i visited (catchment area for trauma the size of ireland?), preceptorship-type program, benign, residents get own office..even the interns get their own desk and computer, fellowships almost anywhere in everything. Possible downsides were name recognition, lack of tumor surgeon, small program size (2 per year), away rotation for three months in Delaware for peds, and maybe location. All of the above were actually pros rather than cons when it came time to rank for me.
The great thing about private programs is that almost anyone who works hard enough on rotation has a real shot at getting an interview/ position. This isn't to say that commnunity-type programs are second rate or less competitive, but it is to say that they generally put a higher value on 'fit' and work ethic rather than numbers, where you went to school, where your father went to school, etc.
Best of luck.
