Preface
Aibaba is a big Internet company I am looking forward to, and it is also the purpose of my choice of this major. Therefore, I still have some ideas for my personal future, and I have been striving for this goal.
Every year, Internet companies like Ali, Tencent, Didi, and Meituan have school recruitment in March and April, and from July to October. When I was recruiting in the fall of my sophomore year, I would send my resume to some second- and third-tier Internet companies, looking for interview opportunities, so that I had a certain interview experience, so that the interview state of the whole person would be unnatural when I was recruiting in the junior year. .
Required skills
Because there is too much content, in order to avoid affecting the reading experience, I directly made the entire content that needs to be mastered into a system recognition map, which is convenient for everyone to read and learn. The high-definition full version can be obtained by private message [Knowledge Map]!
In addition, you also need to master algorithms and data structures, linked lists, binary trees, and heaps (1 billion numbers to find topk) . If it is not a double first-class university, a written test is required to a large extent. Driven by the general environment, algorithm interviews are almost a must.
Recommended learning methods: watch videos, browse technical blogs, read books, learn to summarize knowledge and make mind maps. For example: "Java Core Technology" "Java Programming Thoughts" are must-read books.
A high-quality study note can often help everyone improve their learning efficiency. As the largest "programmer training class" in China, Ali has trained many outstanding industry talents. It can be said that Ali products must be excellent products. Let me share with you Ali's fine works: "Java Knows Nothing to Get Started", "Java Basic Core Notes".
For the convenience of everyone to read, the following content is shown here with text screenshots, full HD version

At last
For me, I want to join Alibaba not only because of the generous salary and benefits, but more importantly, what I can learn, so that I can have a preliminary idea for my future development. Even if you will not work in Ali in the future, you can find a very good job when you return to your hometown with this resume. Why not?
In addition to salary and benefits and learning opportunities, you can also meet a lot of outstanding people. This is your network. It is said that distant relatives are not as good as close neighbors. In society, apart from relying on your own strength, you must also rely on personal connections. In many cases, personal connections can efficiently and easily solve your current problems.
Therefore, I think everyone should take a long-term view and think more about your future. Don't just live in the present. This age is not the age you deserve to be stable. You need to work hard, because the post-90s generation is really not easy. If your own learning ability and self-control are not enough, training courses must be your best choice.
A high-quality training organization can help you solve big problems quickly and efficiently. This confidence also comes from the strength of the lecturers of their organization. It is undoubtedly a good choice to use their experience to help you learn, because you need to fancy For long-term development, please take a closer look!
