Bose1 - Remember we are talking about Advanced Entry (AE) here. The interview coming up in HK is my first with Cathay, known as the Initial Selection. This is a two day process: First day is called the Initial A, second day is called the Initial B.
After this Initial Selection process you are then notified (at a guess it would be a week or two later) if you are invited back for "Stage 2", which is a sim check and group exercise etc.
So in essence, I haven't been notified of Stage 2 as I have not attended the Initial Selection (aka Stage 1).
Hopefully this has clarified things
