Answers to the written test and interview questions of Huawei network engineers

Network engineers are network technicians who master the theoretical knowledge and operational skills of network technology through study and training. Network engineers can engage in the design, construction, operation and maintenance of computer information systems. Then, Huawei recruits network engineers, and what types of questions do the written tests generally take? Let's see:
