Word is that there may have to be a further round of interviews for new candidates, as the number meeting the required standard has fallen drastically short. The maths & VR tests seemed to have caused the biggest problems.
Plenty of experienced pilots passed those very same tests (let's face it, they were very easy!) in 2011 when BA were planning on taking on 800 pilots, including a majority with experience flying for airlines...
Then the bean counters at BA saw P2F as the way ahead and joined the rush to the bottom.
A shame. However, I don't blame people for applying. It's got to be the best opportunity going.
