u0062,
There's loads of data on this forum, even a google search I'm sure will lead you here eventually, there is extensive and I'm sure accurate data out there. I wouldn't bank on any recent information being relayed over the last recent assessments. To my knowledge, many went through all the hoops, some including the sim, only to be told to sod off as they now want cadets. I'm sure you can understand their disappointment and annoyance..of course BA have done this before so no surprises there!!
Maybe your thread would be better suited in 'interviews, jobs and sponsorship' section..this forum (in my opinion) tends to be more geared towards the interests of experienced pilots
Regards, do the research, good luck
