Didn't have many problems with the application process so the most contact I got was during pre-interviews and reimbursements. Brandeis took a bunch of emails back and forth over 2 weeks to settle the reimbursement and I've been waiting on the check for 10 days now. They've been hit by the snow pretty hard so I don't fault them for that.
Vanderbilt was actually pretty helpful. I applied to the wrong program (application said something different than my personal statement) so they contacted me and moved it to the right place.
