If someone's GPA, letters of recommendations, CBSE score (over 65) and class rank were about the same, it would come down to the interview, personality, and whether the residents/faculty think they can get along with you WAAAAY before it would come down to name of school. The only way that choice of school plays a role is that some schools (Columbia, Harvard, UConn, etc.) prepare you better for taking the CBSE. OMFS programs don't care about what the name of your school is unless they've recently had a bad experience with a resident coming from there in the last few years.
