It is the peak of “Golden Nine, Silver ten” interview and job hunting. When I was in Golden Three, SILVER four, I also participated in many interviews. In 2020, they all said that it is difficult to find a job, and the requirements for developers are becoming higher. Some time ago, I have sorted out some high-frequency questions in the interview of Java backend development into a PDF document (1000 high-frequency questions).
