@eberge3
I was going to type up a point by point response to your many posts here, similar to what
@AnatomyGrey12 has done, but I realized shortly after that it would be futile to argue with you.
For everyone else reading this thread, please do not listen to this poster. If you really want to know what the match is like and what matters, talk to 4th years going through the match, residents who recently went through the match, med school deans whose job it is to make sure their students match, and PDs who have to deal with the match every year. Do not listen to people who are not even in medical school yet.
Yes, there is bias against DOs, and this is not exclusive to specialties like ENT, Derm, and Neurosurgery. It is present and pervasive across all fields in medicine. I want to emphasis that this does not mean you cannot match well as a DO, or that you cannot match easily as a DO - it just means that you will have a more difficult time than an MD student in pretty much all aspects of the application. This is something that you should understand going into the process.
There are certainly programs out there in many (all?) specialties that will not rank and/or interview DO students but will take a below average MD student in a heartbeat. I am not saying it is right, rational, or appropriate, but it is reality and again something that you should be aware of.
Letters make an enormous difference, both who they are from and what they say. Do not be deluded into thinking they don't. Your school, boards, and grades will get you in the door, but the "softer" stuff (as it may be called) is what gets you the seat.
