It's a wiring test. 4 different devices to wire up, but you get a demo of how to use the equipment and then an example to follow, so it isn't hard at all. If you can pay attention to a demo and then copy and follow instructions, you're all set.
People have described it before in here and also on Glassdoor as I mentioned.
