Crew_Girl_2:
My experience was: 10 days after my FI, I got an email saying something like, "we are happy to inform you that we will continue to process your application for the necessary clearances and approvals, etc, etc..." That's the email you want to get, because I think there's another one that basically says "thanks, but no thanks." Then it took them 2 weeks to contact me, in which they sent me my contract, medical forms, and pre-training info.
I'm guessing you'll probably get an email within a week.
Hope that helps!
