Foreword:
Believe that all your efforts and efforts will be rewarded to you someday in the future!
First of all, as a leader in the domestic Internet industry, Alibaba has cultivated generations of IT technical talents. Many programmers who want to enter Alibaba Internet companies like not only high salary + generous benefits, but also fancy. The learning atmosphere and network of contacts, these resources will be a wealth for you in the future.
If you want to enter a large factory, you must require your own technology stack to meet the needs of the company or even exceed the needs of the company. The issue of how to improve technology has always been a concern. The IT industry is developing rapidly, and programmers must continue Learning, therefore, even people with the same starting point, after several years of work or study, will quickly widen a huge gap.
I used to do Android development in Kuaishou, and a friend I know works in Ali, and is now a senior developer at the P8 level. So I don't care that this P8 boss is coming to some of his previous Android interview advanced notes, and I will share with you here to see what technical stacks are still lacking in my interview. (PS: At the end of December, I had already moved to Meituan, with an annual salary of about 50+)
The following will introduce some note materials used by P8 bosses. Due to the limitation of article length, each chapter cannot be displayed in detail. Here, I will show the entire note content with screenshots . Friends who need it can get it at the end of the article;
