What did the graduate students majoring in mechanical engineering do in Guiyang John Wan Aviation Electromechanical Co., Ltd.? Do you need to change shifts? Do you have a weekend? thank you

I was a handyman when I first entered. Don't expect to do anything. You don't have to work shifts, only day shifts, not necessarily weekends. If you need to be on duty, you can't put them all. If there is an accident in production and you need technology, you will usually be arranged to take a day off every week, but you will be paid overtime.
