As people who eat melons, we would rather believe in it than believe in it. After all, many things are not groundless.
In my opinion, the reason why Ali, Huawei and JD.COM stopped recruiting people is not the poor quality of social workers, but the scarcity of key experienced talents. Besides, with the development of economy, enterprises don't need so much manpower now, and most of them can completely realize automatic production.
One thing we have to admit is that many hardware college students really have low professional skills and low vision, and there are many defects when they don't work in these big companies. As a big company like Huawei JD.COM Ali, there is no need to pay for them. It is better to recruit some talents with professional skills in turn.
