Operators, or front-line workers, have no requirements. General employers need skilled workers, but if they can't find skilled workers, they also need novices and apprentices. As for what it feels like to work, I don't know. If there are no other advantages, I suggest you start with an ordinary operator. At first, you'd better not be afraid of suffering. When you become a master, your salary will be high and it will be easy. Maybe a technician? I want you to think it over.
