Internet interview must be an essential part of every computer student, no matter how much experience you have in the project, it won't help if you don't prepare the basic knowledge. First of all, let's talk about work.

Three years ago, when I was a fresh boy just graduating from my senior year, there was a huge job fair held in our school, and then I went to attend it in high spirits. At that time, I felt well prepared. I printed seven or eight resumes, each in color. At that time, I asked several Internet companies, including Huawei, Chaochao. It involves many directions, such as hardware fpga,java, algorithm, robot, operation and maintenance and so on. But most of the salaries are between 3500 and 5000. It made me feel good at the time. Because the salary given by other majors is about 3000, which is not a small difference with our major. Coincidentally, I have a relative who has been working in Shanghai for several years, which is also an Internet company. Their company covers a wide range of areas. By the way, I asked about these jobs I was looking for. The result is: he said that it is not very good ah, the salary is too low. His advice still made me insist on taking the graduate entrance examination. He said that by then his salary would double and his experience would be different.

After listening to the advice of my relatives, I still insisted on being admitted to graduate school. I didn't have any feeling at first, which was almost the same as undergraduate graduation, but now I feel that I have chosen the right path, and the gap between graduate students and undergraduates is so large. the starting point is too high, and now any Internet company pays an annual salary of more than 200000, which was unthinkable when I was an undergraduate. Next, let's talk about how I prepared for the interview.

I have been in contact with all kinds of projects since the university, and I have a lot of experience in the project. at the beginning, I feel that I must have no problem, because I have a lot of experience, so I did not prepare the basic knowledge at all. My first application was Meituan's summer intern. It happened that the school was not far from Meituan, so I went to the on-site interview. First of all, the interviewer gave me a test paper, which was all about data structure, algorithm, linux foundation and java foundation. After doing it for an hour, it was estimated that 1/3 would not. I blamed myself for not preparing the basic knowledge at the beginning, and many questions about the data structure could not be answered, which seriously affected the later interview. An hour later, the interviewer came over and asked me how the answer was. I said that the foundation was not ready. He looked at the test paper, and then asked questions compared to the test paper. It was estimated that he had asked for about an hour. During that time, I answered about the basis of java, and the data structure was estimated to give me a four-point mark. It is impossible without review at all. Then there is the basis of linux, asking a lot of questions, such as the meaning of the parameters of the top command. These questions are suddenly confused by me, because I have asked a lot of basic knowledge that I do not use, and many of them have not been answered, which is very embarrassing, because I feel that linux is OK at ordinary times, and I have experimented with the technologies I generally use. I have a strong ability to use them, and they are all Baidu Google on the Internet, and many of them will not be Baidu. I didn't remember many of the questions asked by the interviewer, so I didn't answer many of the questions asked by the interview. in addition, I felt that my linux was good, so I was very hit. After going back, I decided to make up for linux. After going back, I searched a lot of review materials on the Internet. After comparing many aspects, I decided to choose teacher Liu Jing's "this is how to learn Linux". From the beginning, I followed teacher Liu Jing's lessons bit by bit. Some of them were very simple, but this time I was not careless. I also followed Mr. Liu Yun for a brief answer. Here I would like to emphasize that although a lot of knowledge can be easily realized than online tutorials, there are a lot of details that we ignore. For example, a lot of tutorials on lnmp can be realized with one copy and paste. But if you meet a tricky interviewer, we won't be able to answer it, so I suggest you study a little bit more than Mr. Liu's course, you will find that this course is very detailed and specific, and the teacher speaks really well.

About a month later, all the courses have been completed. When you recall the interview questions at that time, you will find that the questions are very simple. I blame myself for being ill-prepared. After Linux is ready, it is far from enough, but there are many things to prepare, such as java foundation, data structure, algorithm, java version, high concurrency, web knowledge, computer network and so on. To put it simply, the basic part must prepare the jvm virtual machine, the principle of hashmap, the comparison of various sets, what are thread-safe and unsafe, how to solve the high concurrency conflicts, the mechanism of locking, the tcp and udp in the computer network, and what is the network structure? why three-way handshake and four waves? The principle of the spring framework, why use it? What are the advantages, disadvantages and principles of the eight sorting algorithms? Another must-ask question is to introduce your project and know how to implement it in detail.

In short, the Internet interview needs to prepare a lot of knowledge points, can not be careless, otherwise many details will be ignored by us, and finally hope that everyone will get their own satisfactory offer.
