I was very excited when I first joined Tencent. After understanding the responsibilities and operating procedures in depth, I came into contact with a project that started from scratch. At present, there is nothing I need to build myself. The meeting said that I need to recruit a few developers. Due to personnel One of my friends in the department was not in the company, so I was asked to interview new employees with another interviewer. Basically they all jumped over from the previous company.
I completed this process in a very serious and responsible manner, which took about 30 minutes. It is mainly a technical interview. In the past 30 minutes, the interviewee and I conducted exchanges and learning. The whole communication process was pleasant but there was no disturbance in my heart.
There are a lot of people who come to interview, and the resumes are all with an average of several years of work experience, but the average level is very disappointing. Actually, the lion asked for 25K. I asked it as expected. In the interview, I didn’t look like the kind of self-confidence that I have had for several years. Years of work experience is just piled up by CRUD, without depth.
In the end, I recruited 2 modest and pretty good ones who can be considered as helpers. I talked about this with a few friends, and they also felt the same way. People are impetuous, and few are willing to do technical work in a down-to-earth way.
As a Java architect, I would like to share some of my inductions and summaries of technology over the years, and share my notes on the skills that a senior Java developer needs to master. I hope it can help those who are interested in technology. A friend who goes all the way to the end!
Let me share this 2021 may be the most complete knowledge architecture diagram of the development direction of Java architects that I compiled. Send a private message to 666 to get the free download address.
1. The underlying source code and design pattern:
Introduce in detail the classic design ideas used in the source code, see how Daniel writes code, improve technical aesthetics, and improve core competitiveness.
Help everyone find the entry point to analyze the source code, and bring a huge sublimation in thinking. Know it, and know why. Make knowledge your own.
2. 36 strokes of software skills and actual combat techniques:
Design patterns are the experience and methods for solving common problems, and they are the designer's sunflower book. These 36 practical cases of design patterns also need to be understood.
3. Distributed microservice enterprise-level solutions:
Distributed and microservices are one of the hottest topics in Internet architecture technology. During the interview process of Internet companies, the interviewer will basically ask questions about the distribution of microservices. As a developer, a programmer with technical dreams, the distributed microservice architecture is the mainstream technology that must be understood now.
4. Distributed microservices and high concurrency:
In the Internet age, how does the system architecture meet the challenge of high concurrent traffic. As a technology developer, how to deal with the skills crisis brought about by technological change. A comprehensive and in-depth explanation based on the technological changes brought about by the evolution process from the traditional architecture to the distributed architecture.
It has been greatly improved in terms of technical depth and technical breadth. Become the T-shaped talent needed by the Internet industry
5. Real project architecture design from requirements to implementation

Use the cloud server to build a real development and deployment environment, with the participation of students, to develop a project involving thousands of people. Introduce big data-related content in actual project combat, and you can get started after learning
1. Ability to independently develop and build distributed architecture systems
2. After completing the study, it is equivalent to having more than 2 years of Internet development experience.
6. Team collaboration management tools
Whether you are just getting started, or you are a senior developer and architect with high talents, you need to start here
1. Master the skills of automated deployment;
2. For Xiaobai who came here, he can quickly improve
3. Bonus points for senior developers
7. Massive data performance tuning reveals the secret
Fully understand the concept of performance optimization, understand the underlying mechanism, and help scientifically optimize the actual combat cases so that you are no longer just a bystander
8. Data structure and algorithm
The status of data structures and algorithms is self-evident for a programmer.
Mastering data structures and algorithms is practicable for both reading the source code of the framework and understanding the design ideas behind it.
