How credible are job advertisements posted on campus?

It is very low, and as students you must be careful. In fact, there are several office buildings in every city, and the merchants inside are all intermediaries, and many of them are scams. Especially the kind of recruitment that appears very frequently is not trustworthy, such as scribes and other nonsense.

There are some units that really need part-time workers, but after all, they are rare. Generally, holiday promotions are more authentic and credible.

In addition, when going to the recruitment site, it is best for boys to go with two or more people, let alone women. I am a person who has been involved in many things, and I may have seen more than you.

Wish you good luck.
