https://www4.gsb.columbia.edu/mba/learnmore/faqs#31"After submitting my application, when will I receive a decision?
In a given application season, the Admissions Office will begin reviewing January and September Early Decision applications once all required materials have been received, and will begin reviewing September Regular Decision applications in December, again, once all required materials have been received. We work to release decisions in a timely manner and decisions can be rendered at any time. Please note that an invitation to interview may extend the review process beyond our 8-12 week goal. "
So for EA, what does it translate to? Decision before December?
