If you are interviewing in December you might not hear from them until February or March. While I was interviewing there Corky made a public service announcement which entailed their oft drawn out admissions procedures - they usually don't fill their class until well into March or early April as they slowly leak out acceptance letters in little batches. This can be a good thing as they stated that such a procedure enables them to give equal weight to both early and late applications. Best of luck on your interview - and hang in there!!
