Is the process of campus recruitment examination in China Southern Power Grid an interview first and then a written test?

The recruitment processes of subsidiaries of China Southern Power Grid are not exactly the same. Except Guangdong Power Grid and EHV, other companies basically have written tests before interviews.

Guangdong Power Grid and Shenzhen Power Supply Bureau only take professional courses in written examination, and both professional knowledge and comprehensive ability should be tested in interview. Moreover, Guangdong power grid will have an initial link, which I also learned in Yicheng. Specific issues can only be scrutinized. Good luck! Hope to adopt, thank you!
