Recently, many fans and friends privately messaged me saying: I survived the cold winter of last year but not the current introversion; I opened the Boss and refused to read a row, and I couldn’t read it back. The answers were basically outsourced, and the salary was not high. The level requirements are also far higher than before; I feel that there are thousands of people competing for a junior and intermediate position in Java at the same time, and the degree of introversion is almost suspicious of life.
And indeed it is:
There are about 4-7 million programmers in our country, of which Java alone accounts for half. The programmers needed by big factories are limited, and high salaries can only be given to a few people, so the competition in Java is so fierce, and involution is getting more and more serious. But in the final analysis, after you analyze some data on the Internet, you will find that the most successful ones are actually junior and middle-level posts, and there are still many vacancies for high-end posts. We can't change the general situation of involution. All we can do is to constantly improve ourselves, adapt to the market environment, and improve our technical level, so that we can get our favorite Offer in the golden season of job-hopping!
Therefore, in order to better help my fans and friends who have always supported me, and to better help you interview job-hopping and raise your salary, the editor is also here today for you to prepare a [2023 version] Java architect interview reference from Ali. guide. Its content covers high concurrency, distributed, middleware, database, data structure algorithm, design pattern and other Java architecture core technologies.
Due to the limitation of the length of the article, the editor uses screenshots to show everyone who needs to get the full version. Friends who need to get the full version follow me, like + forward, and reply to [666] by private message to get it

Interview, hard or not? Is the end result good or bad? It depends on the interviewer's background (aura + skills), mentality and cognition, and communication skills. And some mainstream large-scale Internet company interviews (Alibaba, JD.com, Meituan, Didi) require you to show your abilities during the interview, so as to gain the appreciation and affirmation of the interviewer.
And programmers need to go through layers of interviews when applying for a job. As the saying goes, sharpening a knife does not cut firewood by mistake, and doing a good job of preparation before the interview can help you better deal with the interviewer's questions and emergencies during the interview.
