Sure. But the job market today is pretty much top guy gets the one job and everyone else can hacksaw. I doubt someone became an MD to become an analyst, it may have just happened as their life unfolded.
I have a friend who is a pathologist and has done some work with pharma on the business side. She’d probably do quite well as an analyst, and if the right firm offered her a big salary, I think it’d be considered. I can definitely see how this can happen.
Its like Itera’s refrain, you can make $350k/year as an MD, but you’ll never make the $1mm+ that he makes unless you’re a Wall Street BSD.
