Selection isn't entirely dependent on scores as you might've already known with several other factors coming into play. It's much harder if the candidate is an IMG but NYC programs are relatively IMG friendly
The link below shows an average step score cut-off if you have an account I believe

Jacobi, Monte, Maimo, Westchester, Columbia-Cornell, Kravis (Mt.Sinai), NYU, Cohen's, Flushing, SUNY downstate, Brooklyn Methodist, Northwell are considered to be the good ones imo with most of them preferring AMGs and higher step scores. I believe your friend can get into the rest with relative ease
