First, I know it’s a stressful process, but you need to chill. Admissions staff aren’t out to get you. Hating the school will just make you unhappy.
At most schools, applications are screened as they are completed, and applicants are invited for interviews based on a lot of factors, from stats to mission fit. Once you have had your interview, the process is more like a visit to the ED than a trip to the deli counter—it’s not first come first served. All the applicants who have been interviewed are in the big waiting room, and are triaged for admission, not based on the time of arrival, but on the strength of their application to that particular school (different schools value different things). The admissions committee meets on a regular basis to review and rank applicants. Periodically, they choose a number of applicants to accept. Most schools don’t accept hundreds of applicants at once, because they need to see who accepts their offer of admission, in order to build a balanced class. If you haven’t received an A or an R, they aren’t deliberately ignoring you; you are still in the waiting room.
