Intern year,
4 spend the year at the university med center (gen surg, ortho, icu, radiology...)
The other 4 spend the year at a private hospital that is university affiliated (gen surg, ortho, plastics, neuro, e.r.).
There are pros and cons to each and thus makes it difficult to compare the two. Either way, you get good training.
Assignments are random (you can't pick and choose).
Hope this helps. Good luck in the match.
