What is the treatment of mechanical engineer interns in Kunshan Foxconn this year? Is there room for development?

I started as an apprentice and have to work overtime for 2000 yuan a month. If you study well, it is estimated that you will add a post allowance or something ~ if you count overtime, it will average about 2500 a month. Now the electronic field is basically handled in this way. As for the development space, I personally feel that a big company like Foxconn has no room for development.
