Hi JB88
I had an assessment day back in December and after xmas got the same email saying successful but wont know if there would be a place for summer 2009. However, I eventually received letter offering me the job at LGW and start 23rd Feb!!!!
So just hang on in there this is the norm, at least you are successful and I'm sure you will hear soon. Its a long waiting process but worth it!!!!!
Well done to you and good luck!
