Is the job fair in Dalian Xinghai reliable? Are they all big companies?

The job fair in Dalian Xinghai Convention and Exhibition Center is large twice a year, in spring and autumn respectively. Like large job fairs in other cities, it is more formal! I don't know what kind of company you are talking about! There is a so-called standard for big companies to submit resumes. Article 1: 2 1 1 key universities of engineering recruit graduates. I don't know if it meets the standards of big companies.
