Is State Grid a Monopoly Enterprise? Can't college students without background get in?

Is it a monopoly enterprise that enjoys the policy protection given by the state, thus controlling social production, manipulating and monopolizing the market? There are also some monopoly industries in China, such as salt industry (cancelled), tobacco, power supply, finance and real estate. Because there are no other power grid companies in China and the State Grid is in a monopoly state, the State Grid is a monopoly enterprise. State Grid recruits new employees every year. As long as they meet the recruitment requirements, they can enter, not college students without background.
