As far as hours and overtime, each facility varies. I have no first hand knowledge of Palo Verde, but I do have friends working there. Even if you are dead set on operations, it still might be a good idea to explore a maintenance position. It could be easier to move from one department to the other than to get into the one you want to start with. And if you do get into maintenance vice operations, you might just come to your senses and stay there. Good luck and thank you for serving.
