Got my call this morning although missed it but called back half an hour later for the good news.
I'm in on the 24th, but hoping to be staying at the hotel the nights before and after so for anyone interested in meeting up to network or to get to know each other for the group excercise part of the interview on the 24th drop me a message.
For those that are still waiting best of luck and don't worry. My online status still says invite to pre-selection online test so from the looks of things there isn't any "tells" to look for just yet.
