Yes, people who gets interview prior to Dec 1 will have a very high chance of receiving acceptance, however, usually these are also the applicants who have stellar stats and applied to schools that may be better or less expensive than Case. Case may be their backups. Come Dec 1, they may receive acceptance from their first choice school as well as one from Case and they will most likely reject the acceptance from Case to go to their 1st choice school. This means that although Case may hand out a lot of acceptance letter in Dec, only a few will actually keep the acceptance. Therefore, Case will continue to interview until they can get the class filled. As I mentioned from another post, the % of applicants that get an interview from Case AND will receive an acceptance letter is around 65-70% (This % is pretty high because you have to take into account that not all applicants who receive an interview will attend Case. Hope this answers your question.
