Foreword

Baidu, Ali, Tencent (BAT), the three giants of domestic Internet companies, the dream of every programmer, especially the programmers with 3-5 years of development experience, who have enough experience and have also studied relatedI have always been worried about the product knowledge, but I have no idea in my heart. I don’t know if I am fully prepared. However, friends who have interviewed with big factories such as Ali should know that each big factory has its own interview characteristics, but there are also commonThings, that is, their common technologies, are guiding the development of China's Internet industry. For this reason, when I communicated with a million-year-old architect from Tsinghua University, he said, it is really not difficult, onlyBut it depends on the study skills you have mastered!

Although many people study every day, they are always doing useless work and taking many detoursThe knowledge and technology collected on the Internet are scattered, and learning is a waste of time!To this end, a systematic and precise technical learning and improvement route is provided for reference to friends in need!

This route is the 6+2 strategy that the editor will introduce in the full text: technology + project practice

6+2 (Technology)

1: Multi-threaded high concurrency

2: JVM

3: Design Mode (Tank Battle Project as Actual Combat)

4: Redis

5: MySQL

6: Zookeeper

Projects

1: Ride-hailing

2: Multi-level cache architecture platform for billions of traffic

If you can master these 6+2 and some basic principles, then in a first-tier city, your salary is at least 25K+. If you have not reached this standard, then the first is that your technical level is not yetAt this point of accumulation, for example, if you only read the various materials and interview documents of these technologies, and you want to get 20K, then I can only say, goodbye, brother!The second situation is that your company is not willing to pay so much cost, then, old iron, I think you should know how to deal with it. Next, I will show you the learning graph related to 6+2

Multi-threading and high concurrency
