I don't think there is anything I would have or could have done differently that I can think of at the top of my head. I think one thing students realize well into medical school is that their home school's dermatology dept. is either excellent, good, average, or poor when it comes to mentoring their home students in applying for the match in Derm. Remember, your home Derm residency program is not obligated to take anyone at your school that year and sometimes if a lot of people in your year are applying for Derm at your state med school, for example, that can affect the number of interviews you get since programs can only interview so many.
If you go to a school that doesn't have a great Derm program where you can build up your CV, this that can sometimes effect how well you do in the match. Some derm programs have faculty that really go all out for their students. Some are the exact opposite and won't do anything. I think applicants don't realize how "connections" based Derm can be, so sometimes depending on what your academics are, where you go to school, how much you've gotten published so far, it might help for you to take a year off and go somewhere where you can make that good connection and also be productive.
There are some r
eally good programs out there that aren't NYU, UCSF, UPenn, Harvard, etc. which have awesome faculty, great experiences in all areas of Dermatology, and prepare their residents well, and to top it off, a normal lifestyle in residency where you have time to read. And no the ass-kissing in academics never stops bc academics always has some political forces at work and certain faculty members can be very full of themselves. LOL.
