Having just gone through this, I can say that while possible and maybe even "likely" it isn't a for sure thing. It really depends on a few things: The specialty how competitive it is and how many programs there are, which cities you are targeting ie big vs small, and finally how many places you are willing to interview.
Based on those factors it can change a LOT. For example, lets say you are applying to dermatology, want to live in a smaller city and aren't willing to go on a ton of extra interviews. Well derm is competitive with few programs. So, you would have a LOW chance in this scenario.
However, if you are applying to PMR, want to live in a big city, and are willing to go on as many interviews as it takes then you have a HIGH chance of moving once.
Also, some programs do talk to the prelim med program at their hospital, but even this isn't a for sure thing.
