What is the treatment of Zhujiang and Jinwei Beer (Dongguan) Co., Ltd.?

The salary of Dongguan Jinwei Beer Company is not good, and the supervisor level is only 3800-4000 yuan a month. I once interviewed their safety supervisor, as did Li, production manager Yang and general manager Huang. After the interview passed, they asked me if I wanted to come to work, and I thought about it and gave them an answer. Two days later, I returned to work. Personnel Li surnamed Li said that I should sign the bill and inform me to go to work in a couple of days. And I stood them up.
