Congrats to all those who are successful!
Chin up to those who have not been.
Some good advice has been posted already on actions to take in self diagnosis, such as recalling as much of the process/questions as possible. What would you change about your approach or preparation if facing the same again? What were the interviewers reactions to you and your answers. How much probing was required before moving on?
Go and gain what ever feedback you can ASAP. Be very open and receptive to it. And I REALLY mean that last sentence!
For those looking at EZY et al, take a quick pause before proceeding. If you are spending around £100,000 where do you want it to take you? Do you really want to work for EZY or BA? Is it absolutely vital to be in training this year?
Take stock and ask yourself some very important questions. The FTOs hold back other airline applications until after the FPP has finished selection for some very good reasons. One is resources, but the others are financial. They are a business.
My point is do not go rushing head first into the 'next best thing' without doing some self diagnosis/washup.
All the best to all looking to start a new career in aviation.
