We all know that the IT industry is a gathering place for high-paying people, but it is not easy to become a high-paying programmer. A monthly salary of 20k is a threshold for Java programmers. If you want to break through, you must master more skills.

In the past half a month, the author chatted with more than ten programmers about job hunting, and the market is not optimistic. Among these people, there are many senior programmers with many years of work experience, and there are also newcomer programmers who have just entered the industry. Some people are practitioners of the best Java technology stack in the ecology, and some are young people who are full of confidence and speak directly.
As of the end of 2022, I have been working as a programmer for 3 years, and I have never changed companies during this period. I have stayed in one company for a long time, and I am used to everything around me, and I have never thought of changing jobs.
