There must be tons of openings, since there are over 3500 spots and only ~200 applications for those spots. Or is it the other way around?? Come to think about it, there is no chance there is an opening this late in the cycle, unless someone cancels and all other applicants, who got pass the initial selection and got to the interview, decline (Usually double digits). Then all the other applicants, who never got the interview, are not interested either ( sometimes close to 100 per program). Get working on the next round. Good luck next year.
