Just dinged having interviewed on March 7th.
My best instinct is that my profile wasn't really a good fit for the school (I want to transition from finance to general management), and didn't do enough in my apps and interview to convince them otherwise.
In hindsight, I guess I should have been more thoughtful about which schools I was applying to and being more cognizant of what specific schools look for.
Good luck to everyone else still waiting. They do seem to turn around within two weeks of your interview submission, so at least not that long of a wait!
