Well, your foundation is extremely solid. Between your strong GMAT and your good GPA from your prestigious Alma Mater, you are about as good as you can get in those two items. Your work may not have been as glorious as you liked, whoever, given what you have done, you can probably present it to the schools in a far better light than you have here (And you should of course).
Honestly, as an American female candidate with such a high GMAT, I think you have chance of getting some help from the school. It's hard to predict exactly what or how much, but you are stronger than a lot of their candidates, so there is hope.
The main things you will have to do to succeed here are: 1. In your application make your proposed transition make sense.
2. Make better use of the experience you DO have, both in terms of what you have gained professionally and in terms of what this does for you as you go on towards your goals.
Hope this helps!!!!
