/diy/ - Do It Yourself

why would you be interviewed to become an electrician? You don't need to get a license through a union apprenticeship you know. Not that going union is bad, but going through their pipeline is not the only method (though if they are even open to interviews it means they have significant interest in admitting you as a member, ditto for contractors who want interviews as well).

>what should I expect and prepare myself for during my education?

sticking your arm into a wall and cutting code compliant holes through studs to run conduit through, then installing switches and patching the drill-sized piece of drywall you ripped out to get the drill into position. Pic related, you're going to need a quality flex drill bit because that is what you're going to be doing. Also:
