don't believe everything you hear. I may be wrong about this, but I don't know of any school that completely stops interviewing this early.
Just remember this: Even if a school has interviewed enough candidates to fill the class and then some, not all of them are going to accept the offer of admission, so there undoubtedly will be spots to fill. After that, there are usually waitlist interviews (although Creighton has offered opportunities to be on the waitlist without interviews).
If anyone is saying that a school is completely done with interviews for the whole cycle, they probably got some bad information or are just lying. It's usually the case, from my experience.
