Xingsheng preferred to come to the school for spring recruitment. After passing the written test, Tong Tong went to Changsha for an interview. I would like to use this article to record the experience of participating in the offline interview of an Internet company for the first time.
The boss of the class next door also passed the written test. In the morning, we took the urban rail from Xiangtan to Changsha and arrived at Jianshan Station. After getting off the city rail, take a taxi to the headquarters of Xingsheng Optoelectronics. The city rail station is only two kilometers away from the company and you can see it from a distance. . .
To enter the company, first register your name and ID number at the front desk. Then enter the facial information. Face recognition is required to enter the fence and the elevator. Only when the face is verified can it be illuminated by pressing the elevator button. u1s1 is really good, I have never seen it before.
On the way to take the elevator, I met some company employees chatting. After reaching the 11th floor, Miss HR took us into the lobby and waited. Find a chair to fill in a form, which involves some basic information, such as family relationships, work experience, etc. Among them, I am more impressed by the expected salary and minimum salary. I filled in 6K and 5K. I was thinking that for a junior, the salary should not be excessive. In fact, most of the interviewees were seniors who participated in the spring recruitment. At that time, there were about five or six people waiting for the interview. I heard that there are at least three rounds of interviews for fresh graduates, and some people can’t come for on-site interviews because they are too far away.
(The environment is indeed Nice)
After a nap, I entered the interview room under the guidance of Miss HR. On the road, I saw another hall full of programmers at work. Yes, it is similar to the working environment in the picture above, except that it is on the other side of the house.
There are four interviewers in the room, interviewing different people. Waiting for me is a 30 or so fat interviewer. First come up and introduce myself. Fortunately, I have prepared to memorize it in advance. . .
Before writing the following article, let me briefly talk about my thoughts on this interview: I feel that the interviewer has a basic question. I spend almost half of my time talking about non-technical aspects. I don’t know if it’s because I am in the 22nd class. In fact, I prefer to ask more technical questions. After all, I have been preparing for interviews recently. Like Hashmap, the underlying principle is not asked. . . The harm is not clear, in short, I hope that the follow-up notice can pass.
At the beginning of the topic, the fat interviewer wearing glasses took the resume and started talking.
Q: On your resume, you said that there are several open source projects on Github. What kind of project is it?
A: I said it was the project shopping mall mentioned in the resume.
Q: What technology stack did the project use?
A: Vue+springboot+mybatis+jwttoken+ Bloom filter
Q: Okay, now there is a question: what is stored in the order table?
A: I said the order date, delivery address, product information, etc.
Q: How to store the product information column? That is, the relationship between the product table and the order table
A: Associate foreign keys based on product ID
That's the point here. The interviewer said that if the merchant changes the product information such as the price after the user places the order, then the data in the order is wrong. Then ask me what is the solution? I. . . .
Q: What computer courses did you study during university?
A: Computer network, data structure, operating system, other courses. . .
Q: Then let me ask what data structure you are familiar with?
A: Linked list, queue. . .
Q: Do you know what data structure in java implements a linked list?
A: linkedlist. Then I probably talked about the bottom layer, which is scattered in memory. And its efficiency, let's talk about the difference with ArrayList.
Q: Let’s talk about sorting. What can be done for sorting?
A: Insertion, bubbling, hill, heap sort.
Q: Can you talk about the principle of insertion sort?
A: Not sure. . .
Q: What database are you familiar with?
A：MySQL
Then the interviewer took out my written test papers, pointed out a question related to indexing and return form that I did not make during the written test, and asked if I would do it now. Oh, I wonder how many days have passed since this test. I asked what I meant by returning to the table. After I asked, I still couldn't. It's really too dishonest (艹艹艹). Simply talk about the index types and indexes are conducive to query
Q: In addition to technology, do you have any other experiences in school?
A: I said that I am an equity committee member in my class who is responsible for collecting and disbursing class fees. And joined the two development teams Ticknet and reworld of the School of Computer Science. Then introduced the projects that Ticknet has done, such as the second-hand market and face-to-face sign-in. How many people are using the function of the WeChat enterprise account, and how many average daily visits to the second-hand market are.
I also asked about the technical knowledge about Spring. I said I am familiar with springboot, and then briefly introduced that the springboot convention is better than the configuration. Compared with ssm, it does not need to write cumbersome XML files. And features developed with annotations.
The interviewer said that Prosperity Optimal is second only to Ali in some aspects, and the salary of opening in Changsha is even higher than that of some good Internet companies in Beijing, Shanghai and Guangzhou. Finally, do I have anything else I want to ask?
Q: Is your company's messaging middleware self-developed?
A: Alibaba's open source RocketMQ is used.
Q: When is the internship period?
A: It is considered an internship until graduation and getting the degree certificate. Only after graduation can you sign a formal contract.
Q: How many people are there in the company's R&D team?
A: There are hundreds of people, many of whom are technical experts from major Internet companies.
In the end, there was nothing left to ask, the interviewer told me to wait for notice. Later, Miss HR also told me to wait for the follow-up, and then Tongyi brother and I left the company together with the big guy. . .
When I left the company, I saw a lot of young company employees who went downstairs, most of them dressed in fashion and avant-garde. There is one thing to say, I have long heard that the employees of e-commerce companies are very particular about dressing up, and I saw it today.
