shabon - A longer wait generally seems to indicate good news. It took them 19 days to get back to me when I got in. I know of two or three other guys who experienced the same. It seems that bad news seems to come is about 7-10 days after the sim at most.
Regarding course dates and hiring for this year; they've just about filled the remaining spots for 2015, although there may be one or two left at the very end of the year. The remaining courses for 2015 are all going to be for LGW Airbus apparently. For 2016 the company is expecting to take on another 350+ guys.
