Hi Faiz,
I think the best thing to do at this point is to be positive about the results. In most cases, where you are confident, you may end up being disappointed and where you are not sure like in this case, you get surprise.
I had my interview on March 3rd. First it was network problems that saw the original plan of having the interview via blue jeans changing to a phone interaction. You can imagine the nervousness in such a situation. However, I had to do my best especially since the Prof was very friendly. Let's just hope for the best.
Looking forward to meeting you in LKY SPP.
