Finally, I finished the interview Bible of Java core principles and framework, and successfully landed on the United States in five aspects

When you step on the programmer line “ No way back ” When , I believe you have experienced the baptism of the interview and have been recognized by him , stay Before the interview, are you like any other interviewer , A lot of preparatory work has been done in advance , And the interviewer is usually only in Get a comprehensive understanding of your knowledge structure in just two hours , If you can't answer the question directly , It's hard to fully express yourself , It will eventually affect the interviewer's rating of you , that offer... You understand. .

and How to answer the interviewer's questions “ Pierce to the heart of the matter ” The effect is particularly important , That requires you to be in your daily work , except Hard work outside , There are some possibilities Out of reach perhaps Don't care Knowledge point , Maybe it's when you're interviewing The key to success , In view of this situation, I have compiled a copy of Java Interview must ask the core knowledge + frame , Covering the interview often asked or must ask knowledge points and questions (JVM principle 、 Multithreading 、 Data structures and algorithms 、 Distributed cache 、 Design patterns 、 Network and load balancing principle 、 Distributed transactions 、spring、SpringCloud、 Microservices 、Netty、ZooKeeper、Kafka、Hadoop、Spark、HBase、Cassandra、ElasticSearch、Flink wait )

 Finally, it's over Java The core principle + frame “ Interview Bible ” Successful landing on five sides

summary

This is the Internet , Every moment is full of challenges , In a word : Opportunities and challenges coexist , God knows when a good opportunity will come .

Although there are many kinds of high concurrency in the market now 、 Multithreading or something , But only a few programmers have access to the most advanced technology , Large amount of data , Concurrency, etc , So what do we do? ? In god's hands ? Stop that now the , I personally think you're making excuses for yourself , Like the two materials I recommend today , principle 、 frame 、 The implementation is all in it , You open it in your spare time , Practice on your own , It's also good to exercise your typing speed , Right , Then you're usually well prepared , Then when the opportunity comes, there will be no regret , Right
