After the epidemic, many people are ready to go, confidently preparing to submit their resumes, interviewing everywhere, and choosing the best among different offers.
At the same time, some people will regret that they have not made much progress in the past six months. They are cracking code every day, but when faced with those Java interview questions that are no longer familiar, they just feel familiar, but they can't answer the idea. Compared with HashMap's work Principle, or usage scenarios of volatile, etc.
There are two main reasons for this:
- First, "knowing it is not knowing why it is." Many business applications have been developed, but the logic behind the choice of technology has never been clarified. Therefore, the leaders are not assured of entrusting them with tasks with a certain depth, because they do not know how great their growth potential is.
- Second, knowledge is fragmented and unsystematic. During the interview, I cannot describe the system I developed or the technology used in a complete and clear manner. Therefore, the interviewer will doubt whether he has the ability to solve complex problems and design complex systems.
If you usually work hard, but never look up at these technologies. **Then, you need to sort out the core knowledge points of Java interviews, and prepare in a targeted manner, so that you can draw inferences and talk about them during the interview. **According to the common test points for Java interviews, this Java back-end core interview skill notes can be said to include 95% of the technical points of the back-end interview!
