Take the prospective employee and put him in a room with only a table and two chairs. Leave him alone for two hours, without any instruction. At the end of that time, go back and see what he is doing.

If he has taken the table apart, put him in Engineering.
If he is counting the butts in the ashtray, assign him to Finance.
If he is waving his arms and talking out loud, send him to Consulting.
If he is talking to the chairs, Personnel is a good spot for him.
If he is sleeping, he is Management material.
If he is writing up the experience, send him to the Technical Documentation team.
If he doesn't even look up when you enter the room, assign him to Security.
If he tries to tell you it's not as bad as it looks, put him into Marketing.
If he is wearing green sunglasses and need a haircut, Software is his niche.
If he mentions what a good price we got for the table and chairs, send him to Purchasing.
If he mentions that hardwood furniture does not come from rainforests, Public Relations will suit him well.
