Consultation: 1, salary and treatment of Shaanxi Zhongyan employees; In February 2007, was the recruitment of provincial companies an employee establishment?

I am going to participate in the recruitment of China Tobacco this year, but after reading the recruitment announcements in previous years, I am somewhat at a loss about the written test quality evaluation interview mentioned above. What I want to report is computer science and technology. Can you tell me how to take these three exams and what to take? I am very grateful!
