In recent hiring many engineers, including me are involved in the push and the interview process, after the recruitment, I found that will eventually get the offer, basically see resume has been settled in that instant, a follow-up interview is merely a verification (attention, is to verify, rather than go through the motions), unless you make a mistake in the process of the interview, Or you don’t want to come, otherwise, that offer is definitely available.

People who get offers have these characteristics

1. The school is good, generally 985,211, if the school is average, then you meet the following 2 and 3, there is no problem.

2. In the previous three years, I have worked in well-known enterprises in the industry, such as Baidu, IBM, Tencent, Cisco, etc. Working experience in domestic software enterprises is often not highly recognized, and even far less recognized than some entrepreneurial enterprises that have received venture capital. Of course, if a company that claims to be a start-up doesn’t have anyone to invest in it, it’s almost impossible to expect recognition.

3. Job level: Basically Senior Engineer/Senior test Engineer, Senior XXX Engineer

4. Previous work experience matches the requirements of the current position. For example, the position requires Java, the candidate has previously used Java, the position is iOS/Android, and the candidate has previously worked in this position

However, meeting the above four points and three years of experience can only guarantee you a P6 rating, not necessarily a P7 rating. Then, how can you get a P7 rating? In the cases I have observed, the key to P7 is whether you are well known in the industry.

The reason why popularity is mentioned is that I think this is the easiest for candidates to improve, otherwise, you and the existing Ali engineers to fight for JVM implementation, MySQL optimization, there is no advantage, how can the interviewer give you such a high rating.

So, what if I want to take P8? Solemnly prompt readers, if you personally read this blog, and felt immensely harvest, then you certainly haven’t reached the requirements of P8, because I can see the P8, known in the industry, comprehensive ability, have beyond my words can describe it, I this article, for their part, have no value at all. This kind of culture can’t be cultivated in three to five years.

Now what is P8

P8, usually a first-line Team leader or second-level domain architect, needs to be familiar with the business of one area and be able to spread its influence to other partner teams.

P7 is a proxy for ability, not hours worked. However, generally speaking, after 5-6 years of postgraduate study, one should reach P7. Note that P7 is a technical expert.

Generally speaking, some business architecture, application architecture, product function decision, technology selection, division of collaboration and other issues should end at the P8 level. P8 is the leader of the frontline operations, providing decisions down and effective information up.

There are two kinds of p8, is a kind of management type, is a kind of business types, the former is ali need most, to a certain scale management is the most important because of the company, this kind of p8 to conform to the company values very much, can be determined not to follow the party suspected, listen to the party command can win battles, and often in ali for many years, accord with the requirement of organization for managers, However, there are also shortcomings, that is, I often dare not make decisions and do nothing. Although I am obedient with correct values, I lack the spirit to take risks and make decisions because of the rich treatment and the various ups and downs and personnel changes I have seen in Ali for a long time.

So let’s go back today and look at the whole knowledge of P7, the big system, and there are the following points

Find the right learning route

1. Constitute the skill system of the architect

Two, read the source code, analyze the source knowledge point summary

This chart introduces in detail the source code used in the classical design ideas and common design patterns, first play a good internal foundation, understand how to write code daniu, so as to absorb daniu’s code skills.

Combined with Spring5 and MyBatis source code, with your understanding of the author frame thinking, to help you find the analysis of the source code entry point, a huge sublimation in thought.

Distributed architecture

With your code background, you can learn more about distributed architecture techniques.

Have a thorough understanding of the benefits and benefits of distributed architecture

Inevitability, adapt to market demand, can find some bigger platform development, improve their comprehensive technical ability and salary.

Understand the technological changes brought by the evolution from traditional architecture to distributed architecture, combine theory with practice, and thoroughly understand distributed architecture and its solutions.

From distributed architecture principle, to distributed architecture strategy, to distributed architecture middleware, and finally to distributed architecture practice, programmers can be greatly improved in the depth and breadth of technology, and become t-type talents needed by the Internet industry.

4. Microservices Architecture Skills Summary

With the development of the business, the expansion of code volume and the increase of team members, the disadvantages of the traditional single architecture become more and more prominent, seriously restricting the rapid innovation and agile delivery of the business. In order to solve the challenges of traditional monomer architecture, SOA service-oriented architecture, RPC framework, distributed service framework, and finally the very popular microservice architecture have evolved. Microservice architecture is not a silver bullet, and its implementation itself will face many traps and challenges, involving design, development, testing, deployment, operation, operation and maintenance, etc. Once improperly used, the effect of the entire microservice architecture transformation will be greatly reduced, or even failure.

5. Concurrent programming

From the Java foundation to multi-threading, to the distributed architecture environment of high concurrent access, concurrent programming makes full use of each server processor, with the highest efficiency to deal with each task coordinated work. Thoroughly understand the application of locks

Sixth, performance optimization

As you all know, performance has always been a headache for programmers. As systems become complex and large, performance degrades, and performance optimization is something you need to think about if you want to be a good architect.

So performance optimization topics from JVM underlying principles to memory optimization to performance tuning of various middleware, such as Tomcat tuning, MySQL tuning, etc., give you insight into the nature of performance, a comprehensive understanding of performance optimization, no longer just a spectator.

Java development must know tools

A good architect must have the right tools for himself, that is, to do good work, he must first choose the right tools, whether it is a beginner or an experienced developer. Studying engineering projects will help you and your team develop more efficiently and give you more time to think.

Git: To better manage your and your team’s code.

Maven: Better management of JAR packages, project builds, etc.

Jenkins: It’s better to continuously compile, integrate, and release your projects.

Sonar: An open source code quality analysis platform, easy to manage the quality of code, can check the project code vulnerabilities and potential logic problems (improve the quality of code, improve the efficiency of development more efficiently).

8. Practice a Double eleven e-commerce project

The purpose of the e-commerce project is to apply the knowledge of distribution, micro-service, performance tuning and so on. Only in the project can you consolidate the knowledge and improve yourself. Practice e-commerce projects will use the cloud server to build a real development and deployment environment, so that you can experience the real enterprise project development process from zero to project combat, so that you have the ability to independently develop and build distributed architecture system.

conclusion

To have a chance, you have to rise above the crowd. To rise above the crowd, you have to be different. To be different, you have to do more! Although the dream of becoming a technology champion is beautiful, it requires a lot of effort. No matter it is to Do more, Do better or exercise, it takes time and energy. This process may be helpless and painful, or boring. What I have said before is methodological, but what really determines it is our passion and interest in technology.

So how to learn to quickly get started and master it? When it comes to learning, it is hard to avoid knowing where to start, which leads to low efficiency and affects the confidence to continue learning.

But the most important thing is that I don’t know which techniques need to be mastered, and I often step on the pit when learning, which ultimately wastes a lot of time. Therefore, it is very necessary to have a set of practical video courses to follow the learning.

In order to make learning easy and efficient, today we share a set of teaching resources taught by Ali architects for free. Help you navigate the path to becoming an architect.

This video course explains in detail (Spring, MyBatis, Netty source code analysis, high concurrency, high performance, distributed, microservice architecture principle, JVM performance optimization, distributed architecture) and so on, which become the architect of the necessary content!

But also the framework needs to use a variety of procedures for packaging, according to the basic video can let you easily build distributed framework environment, like in the enterprise production environment to learn and practice.

Add Java architecture group: 6851-67-672, you can get this set of 18, 000 internal textbooks for free!

Finally, be a thinking, thinking, thinking programmer.
