Hello neilferrini, thanks for your question.
I don’t think you need any particular score, per se. I think the usual advice of 700+ overall GMAT score, with 80+% on both the verbal and quantitative sides will do the trick.
In terms of overcoming your low undergraduate GPA, you could do that by citing an analogue that is a better representation of your academic aptitude and potential (e.g., graduate GPA). More important that your quants, though, is your leadership experience in and out of the office. Can you draw upon “moments” when you truly led: influenced individuals and organizations, drove results, took initiative?
I also think you’ll need to clearly explain to admissions committee why you need an MBA to achieve your career goals. In short, what specifically do you still need – in terms of education, skill set, experience, etc. – to pursue your chosen career path that you did not get from your graduate degree?
Best of luck,
