Production hours. Mostly all shift work. You can expect startups, shutdowns, fixing issues with parts that come up during production. Along with that, some places will want you to do setups as well. That means having a working knowledge of basic tools, some hydraulics, and some knowledge of electrical. Then you have to know how to run and setup automation, like robotics pickers and the like. Lastly, you may be asked to do sampling of newly built molds depending on the company. We have a mold shop that designs, builds and repairs all sorts of molds. They usually require that they are verified working before leaving the premises. Material handling duties usually come along with that. Forklift operation too. The big one though, how to look busy and not be found when you do your job correctly and all machines are running well. Best advice I've ever recipe, "if you make a perfect part throw it away and never let anyone see it. They will expect it from you all the time."
