It's almost the same to enter the enterprise, easy and difficult, you know! You can submit your resume and pay attention to the website information. Opportunities are reserved for those who are prepared.
The welfare benefits of chemical enterprises are similar. It won't starve to death if it is not tall.
However, if we want to consider the working environment after entering a chemical enterprise, the nature of the work is very important. Once you enter, you may face shift work, first-line operation, low salary and low status. If you do something else, that's fine!
I hope this helps.
