I don't want to reveal too much but to put you at ease a little bit, We met with each director 1:1, and I found the whole interview to be very conversational, and friendly. It felt like they were trying to pull the best out of me, not trying to trip me up. Good luck!
I got my acceptance yesterday as well, interviewed this week. I felt my interview went well, not totally sure I got everything correct, but felt I was pretty close. I can send stats privately if you'd like. Good luck to everyone and congrats to those accepted!
