IB Analyst to Foundation Investment Analyst - Competitiveness for top 15 program?

I’m contemplating pursuing an MBA in a few years and am hoping to get some outside feedback on how competitive my application would be at top schools. I really enjoy my current role and have no desire to leave anytime soont, but at the same time I can see the potential value in an MBA and this is an option I would like to keep open. Post-MBA, I would likely try to stay In the E&F world, which is a field that may value a CFA equally if not more than an MBA.

Assuming I score ~700 on the GMAT, how competitive would my application be?

Background: I graduated with a BS in Economics (3.9 GPA) from a directional public university, followed by a MSF from a top 50 public university. After school, I spent 2 as an IB analyst at a mid-market investment bank before jumping to an investment analyst role at one of the largest private endowments in the country ($5B+ AUM). I’m sitting for CFA Level 1 in June and will try to knock out all three levels as quickly as possible.
