Did Shenzhou Great Wall Decoration Engineering Co., Ltd. just graduate?

As you said, you just graduated and don't understand the recruitment procedures and standards in the official announcement. A big company can't give you an OFFER without telling you the position. Even if the salary is inconvenient to write, there must be a position. Why else is it called an offer? The tripartite agreement is that the national organization seals, accepts your personnel file and connects you to the national personnel organization. Is it so good to just graduate? How many people want to enter the establishment, but there is no way to spend money. According to the two points you said, I'm sure they are liars.
