Hi,
I attended day 1 on the 20th and have just recieved that happy phone call. They have booked my sim for mid Nov.
On the day the recruitment bod said that although they are not offering any start dates at the moment they are looking to fill the holding pool and may therefore start advertising again, although she would not say how many are swimming at the moment or how many they are looking to have in it.
They also said that at present they had no plans to extend the time allowed in the pool beyond 12 months. For military guys/gals your 12 months in the pool starts on the day of your sim and not your first interview.
Hope this info is of use
Regards
