Is it true that online recruitment for "network technical support and maintenance" is true? I am majoring in science and engineering, but not computer electronics.

It’s not a lie, you don’t have to have corresponding work experience. Network technical maintenance includes computer system maintenance, hardware maintenance, office equipment maintenance, network integrated LAN maintenance, network integrated cabling, attendance machines, and access control equipment installation. Maintenance, monitoring equipment, etc. It depends on what the unit you are applying for mainly does. Generally speaking, it belongs to the IT industry. The main thing is to be able to operate a computer and be familiar with XP and WIN7 systems.
