Why is it still difficult for Internet companies to recruit people with a monthly salary of 20,000?

This should be a different requirement. Generally, 20,000 developers can still recruit them, but I'm afraid your requirements are unusual. At present, in addition to the most popular artificial intelligence, in other development languages, the salary of 20,000 developers can definitely be recruited, unless you are looking for comprehensive talents who knows both technology and management. In this case, you may not be able to recruit, especially some small companies. The requirement itself may be several people, but the salary.

To give a simple example, let's take the post of Java background development I am engaged in. If it's a small company, unless it's an architect, it's difficult for Java development to get a salary of 20 thousand yuan. Even in Beijing, a city with the highest relative salary in the Java industry, it is difficult to get it unless you have more than five years of work experience or are an expert in Java. Of course, if you are in a giant company like bat, it is possible. After all, it is a big company.
