The number of college graduates in the class of 2022 is expected to be 10.76 million, a year-on-year increase of 1.67 million. For the students of the 22nd class, the large-scale autumn recruitment in the second half of this year is the most important way to obtain a full-time offer! For programmers, everyone knows that the difficulty of school recruitment will be lower than that of social recruitment. At the same time, grasping the identity of fresh graduates will also have an advantage for us to enter large factories! In order to help more Java students find jobs, I found the latest Java interview collection from Niuke.com . This set of question banks is compiled from a large number of real school recruitment interview questions. After learning this question bank, you can understand it all There is no problem in thoroughly responding to the interviews of various companies. (Of course, you must add a good project and a thorough grasp and your ability to tear the code strong enough)
Of course, if you have already joined the work and want to change jobs to memorize stereotyped essays, you can also look at projects and algorithms. The proportion of knowledge points investigated in the technical aspect of Java engineers is as follows:
It should be noted that this picture is not absolute, because the interviewer will ask you based on your resume in the actual interview. For example, if you have more projects, you may ask more project questions, or if you say you are proficient, the interviewer may ask you more questions. These. Moreover, this picture is compiled based on the data of the question bank, not based on the actual single interview questions. For example, the basic part will not be tested in all, but will be selected from it, but the whole will involve such test points. However, the knowledge points that must be tested in the interview and account for a very large proportion are Java foundation and algorithms.
It's an interview, when the smiling interviewer asks those Java questions that you are all too familiar with, you just feel familiar, but you can't answer the point. For example, the working principle of HashMap, or the usage scenarios of volatile.
At this time, you may doubt your ability and hate why you didn't review well at the beginning.
This new version of the document has been uploaded on Github for a week and has gained 30K+star Java core interview magic skills (I don’t need to say more about this parameter, how high the quality is) is very comprehensive, including Java foundation, Java collection, JavaWeb, Java exception, OOP, IO and NIO, reflection, annotation, multi-threading, JVM, MySQL, MongoDB, Spring family bucket, computer network, distributed architecture, Redis, Linux, git, front-end, algorithm and data structure, MyBatis, RocketMQ, Netty, Dubbo , Zookeeper, distributed cache, data structure, etc. are very rich in content, and have helped many people win offers from first-tier Internet companies. Let me share it with you.

Proverbs written at the end of the article
read more, walk more. As a programmer, it is said that the career is over at the age of 35. In fact, there is no need to believe this kind of age anxiety. There are many programmers at the age of 35. If you want to be eliminated by the market, first of all, you have value. You have no Without value, no matter what occupation is eliminated by society. Learning will never fail you, and what you get through learning will always be your most precious wealth.
