I suspect the tests for inexperienced pilots are indeed now slightly different, bearing in mind you're testing for aptitude rather than ability. It always seemed odd to test the aptitude of pilots with experience to see whether they've the 'right stuff', but that's BA recruitment for you.
The tests are the same. They are however 'reactive' and as no two people (experienced or otherwise) are the same, they will sit the same tests but have differing experiences. The program adapts to the user's input to give a true test of items such as 2D and 3D tracking, information processing, selective attention and task prioritisation and a couple of other bit and bobs too.
