CobraGirl, you are much closer than you were before the interview. You had an interview. That's a step forward compared to not even being invited to an interview. Instead of being on the outside peering over the fence, you are now inside in the holding pen.
You will have to hold your breath, probably for a long time, but you won't necesssarily die from it. The greatest movement from wait-lists generally occurs beginning in June. By then, med schools have printouts from AMCAS of applicants holding multiple acceptances at that medical school and others. Those applicants are sent letters giving them deadlines to say yes or no; no's are dropped allowing movement, no responses at all are dropped, allowing movement. There is a vulgar expression for that kind of ultimatum, involving "or get off the pot", which you may know but which I am loathe to use in a public forum!
Multiply accepted applicants ought to be thinking NOW of prioritizing instead of waiting until they have a gun pointed at their head. They ought to short-list early, opening places that might be filled earlier by you, CobraGirl, or others chewing their fingernails. Where is all the selflessness that so many premeds profess as their motivation for medicine when they gather acceptances without making efforts to begin making decisions now? Of course decisions can be made without waiting to know all the acceptances that may be offered. It uses a dichotomous choice system. When a second acceptance arrives, compare, choose one to hold and withdraw from the other. If another arrives, compare again, choose one to hold, withdraw from the other. And so on for the lucky ones who get multiple acceptances. The homework for laying a basis for choosing should begin at the interview by "interviewing " the medical school. Your interview is not a one way Q&A session. Speak also to medical students about issues which concern you. Make notes. That way, when later confronted with choosing, you do not have to make a return trip to find out what should have been found out at the time of interview; the alternative is chosing almost blindly, probably using "ranking" or "reputation" as the chief criterion, maybe level of potential indebtedness as another or how close to home it is.
Rear up, Cobra, hiss, spit, spread your hood, start intimidating the ones who are keeping you anxious in the holding pen.
The life of a premed is sometimes a snakepit after all.
May the wind be always at your back!
