We're hiring for maintenance right now, and I've been giving them a motor start/stop circuit implemented in ladder. I've been suprised at what a good indicator it is. Some of the guys that claim no PLC experience mention it looks like a hard wired start /stop circuit. Some try to trace it, which I take as a good sign. Some pick it out for what it is and the rest just stare blankly and then make up excuses or admit that they really don't know despite listing 'PLC experience' on their resume.

Either way it's a simple test that gave me a pretty good idea of what the guy knows without completely overwhelming them.
