I was reading something and the phrase "highly competitive specialties" came up. I've never heard about the competitiveness of specialties before. -What specialties are highly competitive? Neonatology? -What does "highly competitive" even mean? Is that referring to residency match criteria or something? -How are you matched to a residency? Do you apply to them like med school or do they find you? -Is it possible not to be matched? I know that to be a neonatologist I have to do 3 years of residency and 3 years of fellowship after med school, but I am unclear about what these terms mean or how they come about. Basically, after the 2nd year of med school, my knowledge about what it takes to become a doctor becomes fuzzy.
