What does it take to become a circuit overseer?
The Watchtower Bible track Society relies very heavily upon these men to make sure that they have a tight grip on each congregation.
The structure for control that the WT. has in place needs it's eyes and ears to find out whether or not a congregation is following all the rules that the WT has laid out for it. This is the circuit overseer's job, for he is both an observer and an enforcer. They need someone with a critical eye, who can correct deviation.
He must know how to read between the lines, and understand what the WT Society really wants, (which they cannot put it words, for fear of legal repercussions). Of course they need someone that is thoroughly indoctrinated, and does not doubt them at all, or if he does have some little doubts, he will not allow these to distract him from obedience to the Watchtower. He must tow the party line, in other words he has to be a company man, he cannot be an independent player.
He must understand congregational politics, and know how use congregational politics, to carry out the Watchtower Societies wishes. He cannot be skirmish, about encouraging elders to keep the congregation clean(df).
"Ideally" he should have a friendly demeanor, but this must never get in the way, of seeing to it that the Watchtower's policies are followed. He should be able to read fairly well, and have a good memory, in order to give talks that inspire, as well as make sure the friends are following the society's guidelines.
