Is it difficult for PetroChina to test Qinghai Oilfield?

It is difficult for PetroChina to test Qinghai Oilfield. The written test for recruiting college graduates in PetroChina is not very good. China petroleum enterprises recruit college graduates every year, and the main links of recruitment are generally divided into qualification examination, written examination, interview and formula physical examination. Among them, the written test is not easy, because the written test results account for a large proportion of the interview results, and the topic is not easy to score. If the written test results are short-listed, the results are relatively high, there is no problem in the interview, and the probability of successful application is very high.
