Does anyone know the treatment of "Zhenhua Port Machinery"?

Zhenhua's salary for the first three years shows that the monthly salary before tax is:

5000/ month in the first year

8000/ month in the second year

Third year 10000/ month

But only if you work overtime. Accommodation is good, and the working atmosphere is good. But apart from work, you have no time to yourself. I really don't have my own time. I would also like to ask what your major is, which has a lot to do with salary and working environment.
