Most candidates for job interviews these days will encounter a sad hurdle at work. Why does ** say that? ** After working for a period of time, most engineers have completed the accumulation of the most original basic skills, and the technical level gap of everyone focuses on the proficiency in using language, framework and tools. And the difference isn’t that big, and if it is, it’s easy to catch up. However, if an engineer stays in business development and immerses himself in tool proficiency, he will naturally run into a capacity bottleneck. The bottleneck is said in front of that hurdle, jump over, you found a new world, can continue to grow in the next interval. If you can’t jump over it, you may keep going around in circles.

Recently, I accidentally got a Java growth note from entry to architecture given by a big man of Alibaba. This note sorted out 95% of the technical system of Java backend and recorded it clearly, and divided the learning technology by working years!

The following is a detailed overview of Java’s growth from inception to architecture, and how to obtain this quality information.

Sorting is not easy, feel helpful friends can help like share support xiaobian ~ your support, my motivation; I wish you a bright future and continuous offer!!

conclusion

Also doing Java, some people have worked for 5 years without any change in salary, and some people have worked for 2 years with an annual salary of 30W. ** This phenomenon may not have been obvious a few years ago, ** but with the crazy rapid development of back-end technology in recent years, the era of CRUD can travel all over the world is long gone, and the talent level differentiation is becoming more and more obvious.

Competition is always very cruel, after all, becoming an architect is not so easy, the growth of an architect comes from opportunity, hard work and talent! Whether you’re just starting out or just a few years into development, I believe you need to read the above notes on Java from startup to architecture growth to help you in your career.
