After going through the match, I can share some insights:
1.) Step 1 is important, and step 2 is not. Also, there is a difference (and a large one at that) between >250, >260, and >270 on Step 1. It's silly to think otherwise.
2.) Manuscripts are helpful, but posters/oral presentations/grants get no respect. I had about 30 abstracts at prestigious conferences, but got asked about...zero. I also had grants and oral presentations, which were also neglected during interviews. But, I was frequently complimented on bringing so many projects to completion as published articles. Publications in the field is definitely key. I was consistently asked about my pubs in the field, but never about my basic science research (which was also in the field). No clinician wants to talk about a basic science paper they know nothing about during an interview.
3.) Med school reputation is important. Applying from a top 10 med school is a bonus, but anything below that is basically all the same. Top 50 or Top 25 doesn't really help you, but obviously won't hurt you compared to lower tier schools. I assume that this is because there aren't really that many allopathic med schools, so top 25/50 isn't really that impressive.
4.) Med school geography can be very restrictive. Northeast med students get
interviews all over the country. California med students get interviews all over the country. Southern med students get interviews in the South almost exclusively. Midwest med students get interviews in the Midwest almost exclusively. There are obvious exceptions to this rule, but usually it is due to a.) important family members in the field, b.) big wig letter writers, or less often c.) an applicant that excels in
every aspect of their application (scores, grades, research, letters).
5.) Home institution program reputation can help your application. Coming from a top 10 residency program can help your application tremendulously. Below that, you don't get many points for coming from just a pretty good department.
