There are two kinds of job fairs in the school, one is special job fairs, and the other is campus job fairs.

First, in general, the special job fairs on campus are all recruited by enterprises alone, that is, there is only one recruitment enterprise, and the positions recruited are all from this enterprise;

Second, the campus job fair is generally a job fair made by a school or a school in conjunction with a third-party recruitment agency before the graduation season. Enterprises come from all over the country, and the recruitment positions are different and more selective.

If both job fairs have jobs that match your major, you can try both. Experience is accumulated.
