Obviously it doesn't because it's more a test of reasoning ability and intelligence that specific domain skills. The theory is that smart programmers will be able to quickly pick up whatever specialised skills are needed for specific projects. Some people are good generalists. Others prefer to specialize. Employers are free to optimize for their circumstances and preferences I guess.

Obviously, it doesn't. But having estimation skills (which is what the golf ball stuff is about) is always useful, specifically when doing testing. I wouldn't want to hire someone that couldn't estimate what the price of their supermarket trolley shop was.
