If they keep screening out A level candidates and are forced to hire C level candidates because they studied the prescreen questions and are the only group left. You will find competent employees but you are not getting the best anymore.
Why are A level candidates incapable of studying the questions?
Someone who's A level in my book knows how to get the tasks in front of them done. If half the steps to getting them done are beneath them, they do so anyway. If one of the steps is stupid political nonsense, they do so anyway. Someone who is amazing at hard technical problems and refuses to do anything else on principle is not a worthwhile hire.
