This question is best posed to the Adcom members on the MBA forum. Your GMAT score is below par for your target schools and would probably not do any favors to your MBA application. Hence, you will have to justify your candidacy based on your professional credentials, especially a unique set of experiences that you bring to the table. Therefore, the question you need to answer is: What compelling quality (backed by a solid experience) does Arvind have that justifies admitting someone who has twice as much experience as the typical candidate in spite of his below par GMAT score? If you can do well to answer this question then you have a fair chance.
Another key question that you may need to answer is - Why MBA now (after 14 years of experience) and why full time rather than Executive MBA?
PS: I was a bit confused reading about your profile - initially you state that you have 14 years of experience, majority of which is in IT and then you talk about being an account manager in Mexico. Can you please clarify.
You would still have to do the above if your GMAT score were 750, however your GMAT score would have pushed your candidacy then.
