I couldn't agree more about them being a load of rubbish. While I was at OAA the guy who was showing us around made some stupid comment along the lines of...
"sorry we have to put you through these tests but one day people's lives will be in your hands, we have to make sure you are up to the job"
I had to really bite my tongue...
However as was seen with the latest round of easyJet experienced pilot recruitment computer based aptitude testing is here to stay as a selection tool both for ab-initio and experienced crews. There is definitely a knack to passing these sorts of tests so getting to grips with the skill set required for them from the outset will stand one in good stead for the future.
