I pretty much agree with what VoltageGSR has said. To get the big picture, I would reccomend reading the article from the November 2002 article of JBJS about orthopaedic resident selection criteria.
It's an article with a survey of program directors. Now, before anyone starts screaming that the article is hogwash (and there have been discussions abou this article in previous threads), I agree that there are limitations to the article, just like there are limitations to the info/advice on this forum. But it is information, and it is up to the reader to decide for themselves, just like what we're going to doing when we read research articles in the future, whether you want to believe the info or not.
Briefly, some of the things they rank are: rotation at their institution, Step 1, med school rank/AOA, interview, LORs, med school, dean's letter, personal statement, research, undergrad rep, MD/PHD.
I would probably also throw in stuff like life experiences such as extracurriculars, jobs, if you were a pro athelete, etc. The "whole package" is exactly what it means....everything about you that gives them a general or better idea of who you are, what you're like, and whether you will be a good addition to their program.
