Every technical person has a dream of a big factory. I think this is normal. It is not a post-dinner talk but the pursuit of every technician. The technical atmosphere and technical standards of Ali, Tencent, Meituan, ByteDance, JD, etc. are still significantly better than those of some entrepreneurial companies/small companies. If you can practice in such a company for several years, I believe that you can The improvement is still very large.
Today is sharing a full analysis of the Java Autumn Recruitment Interview, including basics, thread safety, thread pool, JVM, collections, Redis, MySQL, algorithms, data structures, distributed, Spring framework, design patterns, etc. 500 Java Autumn Recruitment High Frequency Here are the questions. Although the interview questions and analysis can't fully help you pass the interview, matching the interview outline will give you a review direction and reference!
The contents include:
- Java Virtual Machine (JVM)-the top priority of the interview
- Redis cache, MySQL-data storage must ask technical points
- Spring, MyBatis and other frameworks-popular frameworks, source code analysis
- SpringBoot, SpringCloud-Embrace Microservices
- Zookeeper, Nginx-Internet interview hard skills distributed
- Design patterns, data structure algorithms-programmers must know
Java Virtual Machine (JVM) and performance optimization
As a Java practitioner, when looking for a job, you will definitely be asked about JVM-related knowledge. The mastery of JVM knowledge is an important criterion for candidates' technical depth in the eyes of many interviewers. This JVM and performance optimization learning experience note is not very comprehensive, but it is definitely very useful to review and learn.
Redis learning experience notes
As a Java back-end programmer, you will inevitably be asked some caching questions during the interview. At present, Redis is the most widely used cache middleware. There are also articles about Redis before. This is a Redis practical experience note, including Redis data structure, common exceptions and solutions, distributed locks, Redis clusters, sentinels, etc.
MySQL high-performance database
Nowadays, the Internet industry uses MySQL the most. However, for advanced Web interviewers, especially for job seekers looking for a job under 30k, many MySQL-related knowledge points will be basically involved. If during the interview, your relevant knowledge answers are vague and irrelevant. Basically, most interviewers from better companies will not be interested in you. After all, a slightly larger project will eventually let you go deep into the database, and most of the final bottlenecks will first appear in the database.

Design Patterns
I think the design pattern is no stranger to R&D friends. The core is to improve the scalability and reusability of the program. The pursuit is to isolate changes and reduce the changes caused by changes in requirements as much as possible, thereby bringing Improved quality and efficiency. At the same time, design patterns are also frequently asked questions in interviews. The 23 design pattern knowledge points I have compiled are definitely very profitable for friends who have not mastered design patterns. Friends who have studied can also use it. Reference review!
I also sorted out some study notes about distributed and data structure algorithms. I will not show them here. It is not easy to organize, but I am still willing to share them. The opportunities are all my own efforts. Friends in need can help. After forwarding, more friends went to see this share,
Java back-end study notes map
The map is a display of the learning direction, and it is also a good tool for you to take notes when you are studying. Share some of the Java back-end learning map source files that I have organized by myself. You can also add on it yourself More notes!
