How can the so-called network engineers who are currently recruiting jobs be so demanding? Cisco, Huawei and Ruijie all need to know that there is no specific definition of network engineer.

Network engineers do not clearly distinguish between software and hardware. In practical work, they are required to be familiar with the products of several major domestic manufacturers and commonly used international manufacturers. After all, we often see the products of several manufacturers in the physical layer of the network, but there are great differences in network debugging. There is often cross-use. So this requirement is not very high, hardware is the foundation, and the content should not be too much, but the software content is the core.
