Here was my time line:

Within 8 hrs I got an email saying I was short listed for an interview.
3-4 days after that I was contacted and set up a MIA sim eval for Jan 2012.
Now 3 weeks later I've been contacted again and asked to complete the pre selection Phase 1. It seems like it will be Compass Testing, Reasoning Testing and a short interview, then do the sim a week later. If succesful with all you go to DBX for whatever is left.(I think)
