Is the undergraduate student recruited by Shanghai Construction Engineering overseas business department a regular employee or an external employee? Where do they usually go? What are the benefits of peers? I am the manager of a department of Shanghai Construction Engineering Overseas Department, and my undergraduate questions are as follows:

1, general undergraduate students come in for probation, about half a year, and their performance is ok, but their performance is not good, bye; Immediately;

2. Income treatment: going abroad to do projects, the monthly income is about 8000 ~ 1 10,000 (college students just entered the company);

If in China, the monthly income is about 4000.
