I haven't heard about interviews on the Yale, Juilliard, Michener front for this year. I know the interviews last year for Juilliard didn't happen until May. May!
As far as accomplishments go- don't sweat it. From what I hear, it's all about the piece you send in. There will always be folks applying with credentials a mile long, but maybe their pieces are boring. Just because you've had something produced off-broadway doesn't mean it was any good, right? I've been beating myself up about the draft I sent in, but I have to remind myself- I love my piece. I believe in that piece.
Fingers crossed and good thoughts!
