So, I went digging through old threads and reddit (What's new..I'm always digging), and I actually saw instances of people getting lifted off the waitlist. Granted, it was very few and some threads did not have anyone discuss alternate positions. But, there is absolutely 100% a chance for atleast a couple people to be lifted off the list. It is impossible all 400+ people will be able to attend the interviews, so even though it might only be 1 person lifted off the alternate lift, YOU could be that one person.
Don't get too excited, but know it's not over until it's over. Someone heard back for an interview 3 days before their interview date, so be prepared anyway!
