Hi Raab,
Thanks for your post! You have a great background and are a good candidate for all the schools mentioned. Sounds like you have good management experience at an early age. Don't worry about not working at Goldman Sachs, the IB applicant pool is actually one of the most competitive, so you are actually in better shape than many other candidates.
MIT might be a bit of a stretch, as they are much more quant oriented and tend to favor the banker/finance types. I would actually consider Kellogg, which I believe is a better fit.
You have the right profile - good GMAT/GPA, solid WE, good ECs. Now just focus on your applications and crafting your story, particularly why you want to transition into a management consulting role, and how the MBA will help you achieve this goal.
Something you already know - make sure you apply in the first round. This year is going to be ultra competitive, so getting your applications in early might give you a slight advantage.
Good luck,
NP
