Hi shekharanand,
Most Business Schools will expect you to have 2-5 years of work experience before you apply, but there are some Programs that do not technically require any work experience. In those situations, you have to make sure that your application is strong enough to 'make up for' the lack of work experience though - so your GPA and GMAT score (and essays) become even MORE important.
Have you done any research into the specific type of MBA that interests you? Once you can define THAT, you should be able to find some Programs that match your career goals and situation. If those Programs will accept applicants with 0 work experience, then you can proceed with your plans. If they do NOT accept those type of applicants though, you might have to rethink your approach (and change your timeline so that it will allow you to get the work experience that you'll need to apply).
GMAT assassins aren't born, they're made,
