Hi there,
Thanks for your post. Good luck on the GMAT prep, as that will be a necessary, though not sufficient, component for a successful outcome for you.

Your undergrad academics sound solid; the grad school performance a bit less stellar. Your international experience is a plus. Work-wise, it depends somewhat on what you've accomplished thus far.
One challenge is the fact that you already hold an MBA; that can be a tough situation to overcome at many schools, and you'll really need to create a strong story making the case for the differences between this degree and the prior one, and why you NEED this degree.
You mention a lot of career interests; certainly that may affect your school choices, as might the GMAT. Re: business analytics or data analytics, there are also Masters in those areas offered at many b-schools these days, food for thought. Good luck and keep us posted!
