What is the general salary of senior engineers in road and bridge?

I have worked as a road and bridge engineer in overseas departments of many domestic companies in Africa for several years, and now the recruitment of road and bridge engineers in these companies is announced as follows:

1. Salary of the first-class engineer of China Shipping Real Estate Company: 1500 USD/month, with the salary reduced by 200 USD for each level reduction (there may be bonus if the project benefits well), without overtime pay.

2. The salary of the first-class engineer of China Overseas Company is: 1900 USD/month, with the salary reduced by 200 USD (no bonus) and no overtime pay.

3.

Middle earth; China Luqiao; Companies such as China Railway are basically first-class engineers, with a salary of 1.900/ month, a salary reduction of $200 (no bonus) and no overtime pay.

The probability of an engineer being promoted after applying for a job in a company is about 1%. The overseas departments of these domestic companies generally recruit employees through domestic intermediary companies, and the intermediary companies will skillfully charge your employers at least 20,000-30,000 intermediary fees and 400-/kloc-0,000 yuan/month borrower fees through various means. Working as a left and right road and bridge engineer abroad (except for surveying a lot) does not need to do internal information, but all work as a contractor, because African laws stipulate that migrant workers can only use their own labor, and blacks are particularly poor and love to steal diesel oil for machinery in China projects. Each China engineer manages a working face independently, with dozens of black, managing diesel oil. There is no holiday for working in Africa. You can rest for up to 20 days out of 365 days in a year, and work for more than 12 hours every day, basically from 6 am to 7 pm. Send lunch to the construction site, and you can go to work immediately after eating. The labor intensity is high. Working overseas depends not on technical ability, but on the degree of effort, so the elimination rate here is very high. Every week, the company will give you a task. As long as you don't do well in the exam, you will be eliminated immediately and buy your own plane ticket to return home. There will be a steady stream of newcomers coming to China, leaving you with some workaholics and strongmen who will behave themselves in front of the leaders.
