MIT Sloan is one of "those" schools - the ones that seem to slip into the nooks and crannies of the admissions process.
People don't talk about Sloan as much as its elite counterparts. Nobody immediately thinks about it in terms of being a top 5 program until you start digging and realize, wow, this program is insanely good. Most importantly, because of its unique end-of-October deadline and equally unique two-round admissions process, we would wager that application quality on Sloan apps is far lower than on other top programs (which is a *massive* problem if you want to be admitted there). Candidates often don't even start on their Sloan apps until after the October 3-16 gauntlet of deadlines and then they race to finish because they fear waiting until the "last" round. Indeed, since today is October 4th, it's something of a "last call" for Sloan interest. If you want to be serious about getting into MIT, you had better get started - and that includes bringing on a consultant.
