I would like to ask which job-seeking channels are more effective for PetroChina to recruit summer interns.

There are still many information channels for the recruitment of summer interns in PetroChina. Generally, there are the following channels: First, find job-hunting websites such as job-hunting websites for fresh graduates and job-hunting websites for contacts. Second, visit official website directly. Third, choose internal recommendation, such as alumni friends who work in the company, or find some professional internal recommendation agencies, such as "network job search network". Fourth, call the human resources department of the company directly. I hope you can find your favorite internship smoothly!
