Preface
I have been an Alibaba interviewer for two years, and have interviewed more than 200 people (there are statistics in the system), and now I am leaving, let’s talk about interviewing Alibaba.
1. Academic qualifications are not important in Ali. Basically, it is not a big problem for an undergraduate. More importantly, it depends on which company you used to match with the project experience. Many small companies with backgrounds can also join Ali, because Ali happens to be planning this business. Here, there is no difference between undergraduate and master. Screening resumes is also the first round of personnel outsourcing assistants, the second round of the direct boss, and then the direct boss calls you directly or asks the assistant to ask you.
2. The first aspect is very important. The first aspect of Ali is basically the direct leader of your business, that is, the person you will have the most contact with in the future. After he has passed this point, the professional problem will not be too big later, and this level will also Asked very detailed project details, code and the like.
3. The second aspect is the boss of the boss. He is almost concerned about whether the person is tall, and asks wider questions, which is easy to hang up here. The reason for hanging is that he and the person on the side have different comments about you
4. The various intersections in the middle are processes. As long as you don't go too far, you will be almost fine. Finally, there is hrg. Ali’s hr is the most powerful among all companies, and one person can veto you here. In addition to asking technical and business questions, he pays more attention to so-called "values" such as your personality, stress resistance, and character.
If your level is high enough, or the salary is too high after hrg, there may be hrd, the big boss of hr, to add noodles. Or upgrade to add noodles. Ali's interview process is particularly long, basically taking about 2 months. No way, there are too many people, the department is too busy, and the interviewer has limited time, it can only be so...
The editor is also here to share some of the knowledge points that will be asked in the Java interview. There are still a lot of dry goods, and I will share it with you.
The following will introduce the knowledge points covered by the main content of these data notes. Due to the length of the article, only the screenshot content is shown, if the full pdf version is required
General content of learning content:
1. Architect building the foundation (Linux basics and advanced + Netty framework + Mysql + concurrent programming + JVM performance tuning + Tomcat)
2. Open source framework (mainly related to SSM framework)
3. High-performance architecture (Mysql high-performance storage actual combat + Redis cache database + Zookpeer distributed + message middleware + Kafka)
4. Microservices (Docker+Dubbo+Spring Cloud+SpringBoot)
5. Actual combat of B2C mall project

Technical learning summary
You must develop a clear learning route for learning technology, so that you can learn efficiently. It is unnecessary to do invalid work. It is a waste of time and no efficiency. You may as well follow my route to learn.
Final interview sharing
You might as well write more questions directly on Niuke and Likou. At the same time, I also took some interview questions to share with you. I also got them from some big guys. You may wish to write more questions and make a wave of gold, nine, silver and ten!
to sum up:
Common frameworks such as high-concurrency programming, distributed frameworks, and Spring can be said to be necessary skills for Java back-end job hunting.
Common frameworks such as high-concurrency programming, distributed frameworks, and Spring can be said to be necessary skills for Java back-end job hunting. There are many technical details behind each technical direction. For the development of a distributed system, a variety of knowledge such as distributed storage/database/caching, middleware, RPC, message system, distributed consistency processing, etc. are required.
Faced with so many technical details, I think the systemization of knowledge and skills is the first step in judging whether the technology has passed the test!
