Hello, These are probably really basic questions, but I was hoping the more experienced people could point me in the right direction. I'm a new medicine intern, interested in pulm/cc fellowship down the line but not sure about some of the particulars. 1. What is my best source for reading about fellowship application timing, strategy, general principles, etc? I'm talking to residents and fellows at my program of course, but are there any official sources I should be reading as well? 2. What are the most important factors in fellowship application success? LORs? Step 3? PD phone calls? 3. As a DO currently in an ACGME IM program, how important is it that I take the USMLE step 3 versus just the COMLEX? I believe also taking the USMLE exams was essential in the residency match, but maybe not so much for fellowship? 4. How do I find out about research? I'm not particularly interested in research but I'll do what I have to in order to move forward. I'd like to find out how much is required, what type, when I should be starting, etc. Sorry about the multiple questions! Any help would be appreciated.
