background introduction
Computer major, general coding ability, two internships and one 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. The second internship was a relatively short time to return to China during the summer vacation of my junior year (less than two months), so the internship I was looking for was to do a full-time job in a start-up company. stack.
I am interviewing for a test post, I will apply in early 2022, and finally get the oc in April. During this period, I went through several links such as written test -> personality test -> technical side -> technical second side -> director interview -> OC, and basically completed one link every week. Since the JD interview process needs to be reviewed after all the interviews are completed (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 3 questions were given AC, but I read online that if the score of JD written test is over 100, there will be an interview opportunity. The difficulty of the topic is LeetCode is medium, generally 50 lines of code can be solved, mainly pay attention to the problem of the boundary, the specific topic can go to Niuke to see the analysis of the big guys. The third question took the shortest path, but I gave up because of the delay in the previous questions.
Speaking of which, JD.com's written test is still relatively weak, as long as you usually use more questions to pass the written test, there is no big problem.
personality test
About a week after the written test was completed, I received the email for the personality test, but after I took the first personality test, I was told by hr that I had failed. . I was in a panic at the time, because I knew that Huawei's personality test would turn people off. Fortunately, I had a second chance to do it again. At that time, I read an article about Huawei's personality test on the Internet:
There are a total of about one hundred questions, and it is not possible to return to answer the questions, because some of the questions are to examine the consistency of the examinee's answers to the questions.
Now that I think about it, I feel that the answer I filled in the second time is similar to the first time, I feel emmm. . . Very confused.
It is suggested that you should keep a hard work, not afraid of difficulties and a positive attitude when answering the questions.
technical side
In fact, I have learned that this year’s JD.com interview is much more difficult than before. The interview for the test post involves tearing up the code and explaining the problem-solving ideas.
This year's epidemic and Huawei's recruitment policy reform (increased difficulty: it may be due to the "guaranteed" offer of Huawei's major 985 accounts) has led to an increase in the difficulty of interviews and stricter requirements for recruiters. The following is the specific content of the interview.
(1) Deep digging of the project, comments on the technology used in the project and its advantages and disadvantages. Here, the host summarizes the full-stack experience in the second internship, including vue family bucket, node.js, Mysql storage engine, etc.
(2) The idea of the written test questions and what is the black box and white box.
(3) Data structure questions, here we examine a double-linked list question.
(4) TCP three-way handshake and how to treat Huawei.
(5) Stress test, stability test, database.
Two sides of technology
After asking about the project, I just tore the code by hand, and I got stuck when doing the second question here. . But fortunately, the interviewer was very nice to guide, and finally solved it with difficulty.
(1) Dig deep into your resume.
(2) The number of occurrences of a character in a string.
(3) Given a linked list, delete the last nth node. (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 next point.
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 Supervisor (Comprehensive)
What surprised me was that Jingdong's comprehensive interview did not ask about codes, but only asked a lot of questions about career planning.
(1) Some areas that are not enough in the internship.
(2) How did you deal with emergencies in previous internships and projects.
(3) Views on overtime work.
(4) How to handle the relationship with colleagues.
(5) Perceptions of the workplace.
After the comprehensive interview is over, the status on the official website will be updated as: Hiring is being sorted. After contacting hr, I was told to wait about 4 weeks. . Finally received the OC and negotiated the salary and work location~
at last
In the near future, most of the rest time has been taken out, and I have prepared a small shortcut to the interview in a big factory for everyone. I have prepared a set of software test review interview questions and answers. I know that many students do not know how to review. Know what is the key point in the learning process. In fact, I have also experienced what you have experienced, and it should be because I have experienced it, so I don’t want to see that there are thousands of students who are hurt by this. Maybe this article will not help everyone. Thousands of students, but on this platform, I can help the confused you who are reading this article! I am also satisfied!
I also spent several months collecting and sorting out N common interview questions in major factories. Everything you want is covered here: testing theory, Linux foundation, MySQL foundation, Web testing, interface testing, App testing, management tools, Python Basic, Selenium-related, performance testing, LordRunner-related and other 16 thematic technical points are all real interview questions summarized by the editor in various major factories. Many fans have already won offers from many major manufacturers by relying on this PDF. Here today Summarize and share with everyone!
It took 45 days to sort out the "Software Testing Core Notes", a full 5,000 pages, all of which have been packaged in the network disk. The editor's share may be a bit long. Friends who watch it can first understand the catalog and take it at the end of the article oh.
