Hi there,
Congrats on a great overall score! Sure it would be a plus if your quant percentile was higher, but with a 740 you are ABOVE the average at all the business schools out there, including Harvard/Stanford/Wharton, so that is a nice place to be in! You've definitely proven that you can handle the academic, quant, and analytical aspects of b-school that the GMAT is measuring, so be proud of your score and focus on showing more about YOU via the applications themselves! The international experiences and extracurriculars sound interesting... be sure to focus on accomplishments and leadership through your professional experience, and answer the question WHY and WHY NOW, that you need the MBA, especially given how experienced you are! Good luck!
