Hi there,
Thanks for your post! I'd love to hear more about your 'story' and choices and motivations; how the MBA fits in and why it's necessary... so that will likely be one of the biggest pieces the Admissions Committees would like to know about as well!
On the positive side you have multiple strengths including
-overall GMAT
-strong grades during Masters
-less common work experience/ potential interesting stories and perspectives to contribute (but important to approach it as such and demonstrate that in the apps)
-some involvement
And the following potential challenges:
-need to ensure your overall story flows and makes sense (past + present/MBA = future goals)
-undergrad GPA
-IR
-white American male as mentioned (actually you did not say US so assuming there?)
-at the moment not sure how overall leadership profile looks
I also don't fully know a lot about the details of your work experience; your overall best leadership experiences; how much involvement you have (i.e. hours, recency, etc); and more on the decision to transition your career and apply for the MBA etc.
All that said, if you put together strong stories and apps, I would hope you'd get considered at Booth & Kellogg. For GSB/HBS, it's a reach for basically anyone
but worth a shot. Keep us posted if you have further q's, and/or sign up for a consultation at
