I was involved with hiring plant electricians for a good while. I'd always give them a set of prints, ladder diagrams, etc., and point to things. I'd have them identify what the items were that I pointed at. I'd also pick a certain motor or certain device and say it wasn't running, and by having them look at the prints, give me a couple things they'd check first. I'd generally have them draw out a 3-wire stop/start circuit. I always asked what should be simple stuff like, how do you reverse the rotation of a 3-phase motor, and I'd ask them to calculate the wattage of a 5000 watt 240 volt heating element connected to 208. If that all went okay, I'd throw them some ladder logic PLC printouts and ask a few questions off that. If a guy aces that stuff, he should work out okay as a plant electrician. Let the regular HR people figure out if he's a good fit for the company and if he's likely to show up for work every day, etc.
