Which units will attend the job fair of City College of Hebei University of Technology?

In my senior year, many companies will hold seminars, that is, large-scale job fairs, to talk about how powerful they are, and then submit resumes and interviews. . . . There will be many large and small enterprises. I am a mechanical engineer, such as Xugong, Sany, model crane, and some state-owned enterprises. I feel that the job fair is not good, and many presentations can be equivalent to small VIPs.
