Mission Admission is a series of MBA admission tips; a new one is posted each Tuesday.
As interview decisions are released, do your best to remain calm and let the admissions committees do their work. Although becoming a little apprehensive is natural if you have not yet received an interview invitation, you will certainly not increase your chances by calling the admissions office and asking if they do indeed have all of your files or if an interview decision has been made. In fact, such calls can actually have a negative effect on your candidacy, inadvertently positioning you as pushy or even belligerent.
Admissions offices are increasingly transparent and should be taken at their respective words. If they say they are still releasing decisions, then they are in fact still doing so. If they say that the timing of your interview decision does not signify an order of preference, then it does not. As painful as it is, unless something has changed materially in your candidacy, all you can really do is wait patiently and try not to think about the decision or second guess your status.
