Background introduction
A major in computer science in the United States, with average coding ability, he has had two internships and a school project experience before. The first internship was to do front-end development in an Internet company in Shenzhen during the summer of my sophomore year. For the second internship, because the time to return to China during the summer of my junior year was relatively short (less than two months), the internship I was looking for was to do full-scale work in a start-up company. stack .
I interviewed for a test development position, applied in early 2022, and finally got the OC in April. During the period, I went through several links : written test -> personality test -> technical side -> technical side -> director's face -> OC , basically completing one link every week. Since Huawei's interview process needs to be reviewed (about 1 month), it takes about 2 months from application to OC. The following is the content of the specific written test interview:
written examination
Two of the three questions are AC, but I read on the Internet that Huawei has a chance for an interview with a score of 100 in the written test . The difficulty of the topic is medium leetcode, which can be solved in 50 lines of code. The main problem is the boundary. For specific topics, you can go to Niu Ke to see the analysis of the big guys. The third question tested a shortest path, and gave up because of the delay of the previous questions.
It is said that Huawei's written test is still relatively watery, as long as there are many questions to pass the written test, there is not much problem.
personality test
About a week after the completion of the written test, I received an email about the personality test, but after taking the first personality test, I was told by HR that I failed. . At that time, I panicked, because I knew about Huawei's personality assessment, and I would brush people. Fortunately, there was a second chance to do it again . At that time, I checked an article on the Huawei personality test on the Internet:
There are a total of about 100 questions, and the answers cannot be returned, because some of the questions are to test the consistency of the candidates' answers.
Now that I think about it, I feel that the answer I filled out the second time is similar to the first time, and I feel emmm. . . very fascinated.
It is suggested here that everyone should maintain a positive attitude when answering the questions.
technical side
In fact, I have also learned that this year's Huawei interview is much more difficult than before. In the interview of the test post, it involves tearing the code and explaining the problem-solving idea.
This year's epidemic and Huawei's recruitment policy reform (increased difficulty: may be due to the "guaranteed" offer of Huawei's major 985) has led to an increase in the difficulty of interviews and stricter requirements for the ability of recruiters. The following is the specific content of the interview.
(1) Deep digging of the project, comments on the technologies used in the project and the advantages and disadvantages, here the landlord summarizes the full stack experience in the second internship, including the vue family bucket, node.js, Mysql storage engine, etc.
(2) The ideas of the written test questions and what is the black box and white box.
(3) Data structure problem, here we examine the problem of a double linked list.
(4) TCP three-way handshake and how to view Huawei.
(5) Stress test, stability test, database.
technical side
After asking the project, the code is torn by hand, and here I am stuck when doing the second question. . But fortunately, the interviewer guided very nicely, and finally solved it with difficulty.
(1) Dig deep into the resume.
(2) The number of occurrences of a character in a string.
(3) Given a linked list, delete the nth node from the bottom. (leetcode question 19)
Deleting a node is nothing more than traversing the linked list to find the node in front of that node, and then changing the pointer.
First traverse it to get its length, then subtract n from the length to get the position of the node to be deleted, and then traverse to the previous position of the node.
(4) The process of testing.
Business manager side (comprehensive side)
What surprised me was that Huawei's comprehensive interview did not ask about the code, but asked a lot of questions about career planning.
(1) There are some areas where the practice is insufficient.
(2) How to deal with emergencies in previous internships and projects.
(3) Views on overtime.
(4) How to deal with the relationship with colleagues.
(5) Views on the workplace.
After the comprehensive interview is over, the status of the official website will be updated to: Recruitment is in progress. After contacting hr, I was told that due to the epidemic, I would have to wait about 4 weeks. . Finally received the oc in mid-April 2020 and negotiated the salary and work place~
In the near future, I have taken most of the rest time, and prepared a small shortcut to the interview with a large factory for everyone. I have prepared a complete set of questions and answers for the software test review interview . I know that many students do not know how to review, no Knowing what is important in the learning process , in fact, I have also experienced what you have experienced, and I should have experienced it, so I don’t want to see thousands of students hurt by this, maybe this article can’t help Thousands of students, but you can help the confused you who are reading this article on the platform of CSDN! I am also satisfied!
The content covers: testing theory, Linux basics, MySQL basics, Web testing, interface testing, App testing, management tools, Python basics, Selenium related, performance testing, LordRunner related and other 16 topical technical points, all of which are made by the editor in various major factories. The interview questions that have been summed up, many fans have already won offers from many big manufacturers with this PDF. Today, I will summarize and share them with you!
The editor’s sharing may be a bit long. Friends who watch it can first understand the catalogue, and the information can be obtained by themselves at the end of the article.
