If the information was not volunteered, I have asked and been amazed at some of the answers. Another way to gain an insight is to look at the program's FREIDA listing. They sometimes list the number of interviews granted last year. However, that doesn't mean that they will have been the same for this year.
Also, some programs have said that they would volunteer whether or not I would be ranked (not the rank itself) once they had made up their list.
But, all this means very little, as there are too many variables to work out. The only one that seems to hold is that the longer your ROL, the better your chances.
