Hi Nitin,
Wow, practicing medicine already for two and a half years at age 26 - that is very impressive. There is a trickle down effect in MBA circles that help MDs quite a bit. Consulting firms (especially the big ones) love doctors and they especially love doctors who also know what MBAs know. If you were going into consulting, it would be a no-brainer to apply to Kellogg, Sloan, INSEAD, Duke, Haas, Ross, etc. And I think you would be a top flight candidate to any and all of them.
That said, even with an interest in marketing and consumer goods, you still have a direct tie-in with your pharma background and you still benefit from the "pro doctor" sentiment that the consulting pipeline creates within MBA programs. And your profile is strong regardless of career path.
That said, where you will have to do the heavy lifting is showing where and how you developed the leadership skills that are more commonly associated with pre-MBA fields. I can imagine many scenarios where you developed and displayed teamwork and leadership in your medical practice (running labs or research projects and the like), but those are traits that you will have to bring to the page in your essays (and seek to have reinforced in your recommendations). I have no doubt that you have the ability to do so given your playwriting experience, but the strategy of it is where you will want to take the extra time.
So I guess the short of it is this: the sky could be the limit if you crush your applications. I won't make a plug here since that's what we do, but it goes without saying that if you want to talk more about this, we're here. PM me any time.
Keep up the good work.
Respectfully,
Paul Lanzillotti
