for you, not the electrician - Why are you having the house re-wired?
I would ask him about his strategy for running new wires. How much wall demo will be required and where, etc. I would want to know everything that was going to be cut into. I would want to hear something like (we take every effort to minimize disruption to existing surfaces. We will use the attic, basement/crawl space and unfinished spaces to run wires as much as possible)
Also - When you look at a previous job. Maybe its funny, but one way I determine a quality job is by neatness. Are the wires twisted or flat? if they are flat, neat, labeled, etc. its a sign somone took time and cared.
