since i (voice dripping with bitter, bitter sarcasm) "can't speak english", i was rejected, but nova decided not to extend me the courtesy of letting me know. it took me three phone calls - the first two they were "still processing" and the third one they told me i hadn't heard from them because they had decided not to accept me. this could also be a peculiarity of the london office.
of course, i wasn't even called to an interview - so hopefully they're somewhat more considerate when you've got that far.
but i wouldn't worry about it if i were you, from all i hear it's not hard to get in.
my friend who interviewed got her acceptance package mailed to her within a week or two.
good luck!
