Personal Background:

The following main sharing experience and personal learning methods, will include many PDF documents, such as interview question bank (including answers + analysis), study notes, practice documents and brain maps, etc., can be shared for free, follow the public account below to receive ~
Ali interview experience sharing (video interview, 2 technical interview + cross interview +HR interview)
Due to the epidemic situation, after communication with ALI HR, video was adopted, and all four rounds were conducted by video. Compared with the live interview, the video interview was a little more relaxed, with less tension in the process and a more natural way of communication, without too much sense of pressure. As long as the technology was ok, there was basically no problem, so that I passed the interview successfully.

How to prepare to get the Offer from Ali?
Step1: prepare a good resume
If you want to get the Offer from Ali, you must first have the opportunity to interview with Ali. It is not an easy thing to get the interview opportunity from a big factory, while the resume is the key to pry open the door of the interview. Whether the key matches depends on whether the resume is excellent. Many college graduates do not know how to make their own resume, just download a copy on the Internet, change personal information. In fact, the resume of the big factory interview is not about your personal hobbies, nor what associations and students have participated in school, but more about your personal practical ability. Therefore, a good resume should include your skills, whether you have internship experience, what projects you have participated in, what project problems you have solved and so on.
Step2: suggest your soft power (knowledge and technology)
The second key will own strength strong, whether you are fresh graduates, or work for several years, the school recruit or club, hiring is always strength high, that is your knowledge reserves, your technical level to meet the requirements, and the only way to improve its soft power is: learning.
Below I will share some of my personal learning documents, friends who need to choose to obtain:
Java core knowledge
Java Core Knowledge
Micro Services (Combat Series)
Other ali edition ebook materials
Step3: brush items
Now that is going to interview, then without brush, in fact home after the Spring Festival, where also can’t go, my own brush is a lot of interview questions, so during the interview process to accomplish know fairly well, basically be clear that the interview will be asked about what knowledge, what high frequency problem, so the brush problem is very important in the process of the interview preparation.
The following is the interview question bank that I, Ali, kept after the interview:
Write in the last
Many people lament the “uselessness of study”. In fact, the reason for the uselessness theory is that what one wants does not match what one has learned, which means that one has not learned enough. No matter in study or work, you should have initiative, so if you have a big factory dream, then you should work hard to realize it.
All the above learning materials are free of charge. Finally, I wish you good health and a smooth offer!
