amypoka, to be honest, no one could ever predict the perfect profile to get admission at M7 schools. A few things, your years of work experience are less important than what impact you made during your work tenure in your company/companies. Second bachelor’s or master’s both are gonna to raise questions about why you chose to do the degree twice. Just make sure you have a legible answer. 780 is quite a dreamy score, but no school want you to get 780 to get admission. GMAT is just one factor... Your GPA, Your Volunteering, Extra-Curricular, Work Experience, Your Essays, CV... A profile is a mixed recipe for quite a lot of things, you gotta decide which you can do better to set off what you can’t.
