Lets just pretend that this is working to filter good candidates.. even then good software have a lot to do with team work. Its better to have people who are experts in things that the product need to be good at, but also less expert in a certain field but that will do other parts of the product, than you have to manage the group work properly.. My point being, you need people with a myriad of skill sets, and some of them don't even have to do with expert knowledge needed in some areas. Also you might have an expert in storage for instance that do poorly in certain tests giving he never needed to work with those kind of algorithms. So in the end the company ends with the same type, the same kind of person, and how can you make a great team that needs people with different skills doing distinct stuff, if you optimized your hiring to filter for one particular type?
