You hear employers say, you must prove yourself. I agee with the statement on it's face.
However, HOW MUCH is required to satisfy you? Does a guy need to install 4, 10, or 1000 furnaces? Does a guy need to lay 100 miles of ductwork BEFORE you think he has proved himself?
I don't mean to sound of the jerk. I am just looking for some insight. Are your expectations decent, or are they pie in the sky?
