What are the recruitment rules of PetroChina? Miss the campus recruitment, is there any chance? Is it only for fresh graduates?

It seems that you are a fresh graduate. Generally, state-owned enterprises such as PetroChina only go to campus to recruit fresh graduates and recruit people with work experience at social job fairs. So we usually miss the school recruit, and freshmen don't have a chance to go in. However, there is no need to be too sorry. Few people have been recruited by state-owned enterprises this year, and some state-owned enterprises have even cancelled their contracts. Take the oil service company as an example. Slightly relax the choice. You can go to the oilhr website to have a look
