Well done on getting through your interview Cuong... now the `waiting game' begins. Welcome to it !
A lot of new applicants who are about to attend their interview will thank you for adding more detail about the interview, but a little hint.. you are also up against about another 99 people for the highest spots on the OOM list, so you've perhaps just helped out a few before you even have your place on the list :-). But very nice of you... haha.
