The selection mode has just changed recently. You first are invited for the SIM ride and the interview. If you pass, the'll notify you about one week later and you're invited for the second race: assessments and psychometric tests. After that, cross your fingers and wait for the magic phone call.
I've heard quite different statements about the time you will be called. Friends of mine got the call just two weeks after the assessment, myself had to wait 10 weeks !
The current failure rate at Crossair is about 60%. Good luck to you and hope to see you there in the future (I'll start june 5th)
Cheers
