Business owners would love if there were some exam which accurately informed them about who to hire, and there has been no shortage of attempts to create such a thing. The problem is, most of the characteristics needed seem to be things we don't understand, or don't know how to quantify. Greatly complicating things is the fact that you often don't need to know anything in particular to succeed. There is no shortage of people who learned on the job and became successful. Filtering out such people with an exam may badly damage your hiring.
