Hi Victor,
Unfortunately I don't have much expertise to tell you how to convert an Indian GPA to a U.S equivalent. Of anyone with a good GMAT and good work experience can be competitive at a top school, but you'd need to have more details on how high of a GMAT and what kind of work experience/progress to get more substantive feedback. If you are planning to work for a few years, I suggest concentrating on adding new skills and demonstrating leadership wherever you can to help your application down the line.
Best of luck,
Daniel Richards
