Lecturer and teacher Scott McCloud once said this to the effect of hiring practices, how there are three anchors from which an employer of any variety must seek out among potential employees.

To turn in work of professional and skilled caliber, to do so always ahead of deadlines, and to be easy to deal with generally.

A person only offering one is not providing enough to make their employ worthwhile or long-lasting, while the chances of someone realistically offering all three are extremely rare. So, the idea is to look for somebody what can comfortably guarantee any two of the three anchors. For example, a person may only submit average-quality work, but if they are reliable for at least that much and are easy to work with, then they are employable. Or, a person might be notorious for blowing schedules, but if they are always friendly about it, and their end product is always outstanding even though late, then they themselves are worthwhile.

But no psych test in the world can guarantee with 100% accuracy exactly how people might work together. Too many variables and too many subjective variables.
