In my opinion, I think you have to do really bad on your interview to get rejected right away. Otherwise, you will most likely be put on the waitlist or on hold. Your number on the waitlist however, will most likely be unknown, it could be high, it could be low. Most schools don't tell you where you stand because they don't want you to feel bad. For example, What if you are the 26th person on the waitlist and they have 25 seats available and you didn't make it?🙁 It would suck real bad, right? Confidence killer😀
Each school will only have so many people on the waitlist so after all the interviews and everything is done at the end, they will reconsider the people on the waitlist. By that time, they will notify people to see whether they are accepted, waitlist or rejected. I hope this clarify a bit about this whole process for you.
Good Luck everyone!😍
