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?
I don't think anyone, except the AdComs, knows exactly what the timeline is. As far as we know from this forum, all of the applicants from the States are still waiting for some sort of a change in application status. There are a couple of applicants in Europe who got interviewed. I guess the AdCom just wanted to keep the answer to this question as broad as possible, so there are stairs to step down just in case if anything happens.
