I interviewed there on the 24th as well. I asked April (one of the two assistants) and she said that as of that day, they had accepted 19 out the 42 spots (I was quite amazed at their selectivity). But April also said that they would call the students whom they want to offer spots because they need to look out for important mail, and those who are wait-listed or declined would receive letters without a call. One last thing, she said that they wait-list about 40 people. I hope that helps.
