What is the treatment of Wuxi Hengtian Printing and Dyeing Co., Ltd.?

I have already had an interview. Foreign trade business, salary 1500 basic salary+commission. The Committee refused to disclose what the proportion was, and the estimate was not high. There is a comment on the internet that I want to practice in an advanced workshop for one month. It is said that overtime is very common, and the overtime pay is 1 yuan an hour. It is estimated that the welfare will not be much better, and I think the environment of the printing and dyeing factory is very poor.
