So like most I don't know exactly what specialty I will pursue, but I know I am interested in internal medicine and pathology. I may find some other interests in medical school as well. I have some questions about what happens after medical school and residency. If by chance I pursued internal medicine and wanted to do a sub-specialty, how does one pursue a fellowship? Let me clarify my question.... Do residents typically go directly into a fellowship (if they so desire), or do they work in their residency field for a while? Or, is this one of those things that are different for everybody? If so, why would some choose one way and some choose another? How does the application system to a fellowship work? (I feel like I understand the match somewhat for residency, but application to fellowship is more cloudy to me). Fellowships are interested in those that have done research in the field, correct? When do many perform this research? Medical school? After residency? I ask these questions because I'm interested in learning more about Hematology/Oncology and would like to learn more about the pathway to IM subspecialties.
