At last

I have seen many technical leaders meet older programmers who are in a period of confusion during interviews, who are older than the interviewer. These people have some common characteristics: they may have worked for 5 or 6 years, or they write code to the business department repeatedly every day. The repetitive content of the work is relatively high, and there is no technical content. When asked about their career plans, they didn't have much ideas.

In fact, the age of 30 to 40 is the golden stage of a person’s career development. You must have your own plan for business expansion, technical breadth and depth enhancement, to help you have a sustainable development path in career development. Not to stand still.

Keep running, you will know the meaning of learning!
