I have interviewed for the same position as you, and some basic questions are easy to be asked, such as computer maintenance, network maintenance, network monitoring, IP address setting, and preventing logging in to the external network. Have a certain understanding of other office equipment. These are the basic skills for this position. This job belongs to the technical category, and it is less likely to encounter similar interview situations without asking professional questions. As for the examination room, it's hard to say. It depends on the place, not the main aspect. The focus is still on the establishment of the network, the principle and management of routing, hubs and TCP/IP. Please review the relevant knowledge and wish the interview a success!
