I would much rather hire a chap who says 'Hi, I'm Bob; show me what I can do to help' than one who waxes lyrical about his skills and experience. If you've got a brain and the right attitude, the amount of experience you might or might not have will soon be forgotten.
With a good team it will take a week to learn how to be useful, at which point you can stop worrying about pulling your weight and start concentrating on soaking up electrical working practices. I remember setting off up a ladder to wire a terminal box, getting five or six rungs up and realising I had left my cutters behind. As I hesitated something caught my eye; it was the new guy holding the cutters up for me to grab. Needless to say, he was soon running jobs.
