I express-posted my application on a Friday afternoon and had received an Email invite to Stage 2 by Monday evening.
Stupid thing is that I had been sitting on the application for over 2 years before I sent it
To answer the next question, I did the testing on a Thursday and again I had an invite back for Sim, interview, medical the next Monday. The Sim etc was scheduled about 6-7 weeks after the Psychometric testing to allow time for all the security checks etc I imagine.
How long till the next bit? I'll let you know
For the record - I had about 4000TT, 1500 instructing and 1100 multi CHTR.
