What is the salary of cost personnel in Shandong engineering consulting unit in January? More than three years' experience

In our company, the cost is around 4000. However, there are few holidays and I have to work part-time. If you have this certificate, try not to be a supervisor. The construction and the owner's treatment are much better. I suggest you go to companies like China Railway, China Construction and China Communications. Everyone is short of people. Run more by yourself, and don't be bored when looking for a job. No need to add points, they are all in the same industry, I don't know who uses whom, hehe.
