Versailles for the first time in 2021! After 2 months, Ali technical officer "pro code" Java core mind and brain map + core knowledge collation, successfully joined the big factory

In 2021, I can get offers from 5 major companies so easily. In fact, all these credits are attributed to this Java core mind map of the Ali team . I will share it here today, and I hope to help more friends get it. More high-paying offers;

This article is divided into two parts

1. Alibaba Java Mind Map
2. Core summary after 42 interviews

Two points that help to get a high salary

1. In many short interviews, the interviewer cannot know your specific technical level. But if you can give the address of your github or blog, it will make the interviewer's eyes shine. Moreover, the long-term update of the blog can summarize and review technical knowledge, which is of great help to the improvement of technology.
2. In many cases, the person who interviews you is not necessarily the level of your skill. The number of projects you have done is not the most important thing. It is more about your ability to express and understand. The interviewer does not necessarily understand what you do. But you can perceive your ability to express and understand. When expressing project experience, you need to tell from the requirements, architecture, technical points of the project, and the modules that you are responsible for developing. It is especially important to describe the modules developed by yourself. It is far more important to finish one item clearly than to finish ten items vaguely. (I think you all know how to make rockets during interviews~)

Core summary after 42 interviews

Only by constantly summarizing and constantly looking at one's own self-checking and filling vacancies can one become stronger;

Just like the two tips at the beginning of the article, I will go to the website to review the latest interview questions before each interview. After the interview, I will review the experience and slowly develop a habit, condensing and condensing. Summarize and then summarize, after a lot of hard work, this real interview question has been formed; (part of it comes from Likou, part from the interview experience, and part from the sharing of friends)

Because there is too much content, the following is also shown in the form of screenshots;

There are too many interview questions, and the catalog has dozens of pages, so the catalog can only show part of the content for everyone~
