preface
According to the data, Alibaba has been rated as the most popular Chinese Internet company for three consecutive years. In fact, Alibaba has certain representation in both technological innovation and social value creation. In the industry, many Internet enterprises also regard Ali as their benchmark, and more and more “migrant workers” also hope to work in Ali.
Mention ali, believe that is not strange for most programmers, ali, after all, the use of technology always walk in the forefront, programmers and have also been to a line of Internet companies such as ali requirements as the standard, so need what kind of person, ali became the development goal and study direction of many programmers.
In fact, The development of Alibaba is inseparable from the company’s employees, it is worth mentioning that alibaba’s programmers in addition to finishing their own work, but also take time to improve their own technology. Recently, Ali ushered in a milestone, the first Java architecture technology growth notes, both theory and practice, by the industry rating “diamond”, can be said to be a programmer must!

Soft skills architects should have in the workplace
As an architect, solid technical skills are essential, but only technical knowledge is not enough, but also have certain soft skills in the workplace, which includes two aspects:
1. Self-cultivation
As an architect, first of all, you need to have a clear understanding of yourself. The so-called self-cultivation means that you need to have a clear understanding of your career development, know your current situation and future positioning, and know that you are no longer just a programmer, and know how to spread value.
2. Project management
Architects, in a project, in addition to the development ability, also need to carry out certain project management, to improve their own management ability, know how to manage the overall situation in the project, joint efforts.
Viii. Secrets of Alibaba interview
1.Alibaba Interview Clearance Manual:
- Interview experience and skills: the interviewer proverbs + interview experience exchange + enterprise interview strategy
- Interview technology conquer: Java basic knowledge +Java Web+ database principle + design pattern + data structure and algorithm + mass data processing + source interpretation
2. Real questions of Alibaba’s past interviews
conclusion
Every programmer has a big factory dream in his heart. No matter ali or Tencent, the technical requirements for programmers are relatively high. Apart from academic background, whether your technical level has reached the standards and requirements of Ali? If you have a big technology gap with the rest of the industry, and you have no idea of changing the status quo, it is only a matter of time before you are eliminated by the market.
So, whether you want to get into a big company or have a good salary, you need to take yourself seriously. The above Java technology growth notes, I can provide to you for free, I hope that when I help you, you also take the initiative to help yourself.
