Does CNOOC’s written examination notification come in batches?

No. CNOOC’s written test notices are sent in bulk via text messages to uniformly notify those participating in the written test. Therefore, CNOOC’s written test notices are not sent in batches. CNOOC refers to China National Offshore Oil Corporation. China National Offshore Oil Corporation is a very large state-owned enterprise (central enterprise) directly under the State-owned Assets Supervision and Administration Commission of the State Council of China, headquartered in Beijing.
