I recruited Ali in the fall of September 20th. In order to help more friends come in, I will share the main points of the interview that Ali interviewer told me.
Don’t talk nonsense, go straight to the topic
Key points for passing the Alibaba interview
Key 1: Review of basic knowledge
-
Basic knowledge of java
-
The underlying principle of Jvm
-
computer network
-
operating system
-
Data structure and basic algorithm
-
Database knowledge theory
Process experience: This time is very painful, a lot of basic knowledge needs to be reviewed and mastered, and the knowledge points are very detailed, making it difficult for students to master. However, this knowledge accounts for about 80% of the interviews at major companies, and it is precisely these basic knowledge theories whether you can pass it. In this process, the main difficulties are java, concurrency knowledge, jvm principle, http, tcp protocol, network protocol architecture and its various layer functions, basic theory of operating system.
Focus 2: Commonly used technical framework
-
Spring
-
SpringMVC
-
SpringBoot
-
Mybatis
-
Dubbo
-
Rocketmq
Process experience: These technologies are basically used by companies very frequently. For interviews, you must master the use of these basic frameworks and have a certain understanding of these framework technologies. If you can have a deep understanding of these framework technologies It would be better to understand and make some improvements.
Key Three: Basic Algorithm of Data Structure
-
Basic algorithm
-
Tree knowledge (balanced tree, b tree, b+ tree, red-black tree)
Process experience: interviews are often asked, mostly in the form of algorithmic questions, so in the process of preparing for the interview, go to LeetCode to brush up questions.
Key 4: University projects
1. Review each module of the project
2. Review some of the technical knowledge used by yourself
3. Find the problems in the projects you have done and try to improve them
Process experience: The university project reflects one's programming ability and programming thought very well. It is also a frequently asked point in interviews. I suggest that students should not be idle in university, write more projects and participate in competitions.
Key five: mentality
Process experience: Teacher Ma said, “Today is cruel, tomorrow is cruel, and the day after tomorrow is beautiful, but most people die tomorrow.” During this process, you must have a balanced mindset and relax yourself so that you can concentrate on reviewing Various knowledge points. Hold on for a few months and you will find your own growth.
to sum up
Pay attention to computer basics . Be proficient in the skills required for one's own delivery position, and have an understanding of the knowledge required by other positions.
Algorithms add points. Many people don't realize the importance of algorithms. Foreign companies are asking algorithm questions. The algorithms of major domestic companies are now also indispensable. It can be regarded as an industry outlet, and those who master algorithms will get more opportunities.
Pay attention to technical vision . Technical vision is a point that everyone tends to overlook, including depth and breadth. Many major interviews including Alibaba attach great importance to this. Some people answer the interview well, but leave the interviewer with a narrow vision.
Write the things you are most familiar with on your resume . If you just use it and don't understand his principles, you will suffer a lot during the interview. The project is the same. It is best to prepare in advance the areas that may be asked in the project, including the logic of function realization, and what are the advantages of this realization.
The interviewer usually asks some open questions, which is also a test of your thinking development ability and multi-faceted thinking ability.
Never fight an unprepared battle! Prepare early, prepare more!
At last
The main points of the interview have been told to everyone. If you have a small partner who needs relevant learning materials, you can download it for free by adding the assistant VX (gyhycx7980) as shown in the picture below!
Face-to-face, interview questions
JVM related documents and video materials
Algorithm related documents and video materials
ps: Zuo Shen's "Programmer Code Interview Guide" is really very nice
Other related learning materials
ps: I’m too lazy to list them one by one. After a small partner in need helps with one-click triple connection, see the picture below and add a small assistant VX (gyhycx7980) to get it and download it for free!
Preparation before the interview is very important, especially as it is written on the resume. Many people say that the interview is a rocket, and the job is screwed. They feel that they will still do the same job after entering, and they don't pay much attention to the interview. It depends on the interview to know whether you can screw the screw, and the interview depends on how much salary you can get.
I hope everyone can pay attention to the interview and don't waste your chance!
