No need for verbal reasoning - just grunt! No need to be clever, no need to use your brain - when doing the job you'll only follow rules. So all you have to do is write with the crayons provided "Errm" to every question and you'll pass. And when you get the job, which you will, just be totally unpleasant to everybody you can and you'll fit in with the rest of your colleagues. If you really want to be nasty, you could run bets with your new colleagues on how unpleasant you can be with members of the public before getting reported. But please don't expect any respect from anybody. And don't expect any crews to be pleasant to you.
