Interview Technique

An engineer, a physicist, and a lawyer were being interviewed for a
position as chief executive officer of a large corporation.
The engineer was interviewed first, and was asked a long list of
questions, ending with "How much is two plus two?" The engineer excused
himself, and made a series of measurements and calculations before returning
to the board room and announcing, "Four."
The physicist was next interviewed, and was asked the same questions.
Before answering the last question, he excused himself, made for the
library, and did a great deal of research. After a consultation with the
United States Bureau of Standards and many calculations, he also
announced "Four."
The lawyer was interviewed last, and was asked the same questions. At
the end of his interview, before answering the last question, he drew
all the shades in the room, looked outside the door to see if anyone was
there, checked the telephone for listening devices, and asked "How much
do you want it to be?"
