Great point, David!
I would also like to add...The human factors that go into a decision-making process are the perceived ability of the other person to be a self-starter, their perceived intelligence based on conversation, your perception of their ability to get the job done based on conversation, their past history of success, their demeanor (including their attitude), their willingness to work hard and get the job done no matter what, and finally, and perhaps most important, your perception of their ability to fit into your existing team or family. I, also, find these to be important.
