What is the written interview of Longteng Optics (Foshan) Co., Ltd.?

The salary is ok. If overtime is included, there are three or four thousand a month. According to their human resources supervisor, there is a colleague in my dormitory who works in human resources and knows their supervisor. As for the exam, it is not very clear. You can call and ask! However, in the current economic crisis, I don't know if I can recruit people.
