Hi madhurchadha,
Thanks for writing in. It seems that you have a diverse set of community and extracurricular experiences to draw upon in your application -- between your NGO work and YouTube success. I suggest you emphasize these heavily in your application as they can all help differentiate you from the rest of the male, Indian, IT cohort. It would be helpful if this experience fits into your goals and your "Why MBA?", as the schools will want to learn about your vision beyond engineering. Write those essays well and with your great GMAT score I think you could be top-10 competitive.
Best of luck!
