They said at my stage 2 they are in the process of changing the essay question part. It now comes after stage 2, before the interview (stage 3). However, if you have already answered the questions if you applied a while ago, then you won't have to do them again.
I got knocked back at stage 2 but invited back in 6 months. Does anyone know if I have to fill out the application again, or is it just a point of asking them to reactivate my application and then rebook stage 2? Am I anymore likely to pass the 2nd time?!
