Student C – Student of the 23rd full Stack Linux Operation and Maintenance Engineer Class of Pinke College, majoring in Biological Science at Grade 16 of Zhongkai University of Agriculture and Engineering


First, the school situation

My major is biological science. I was transferred to this major as part of the college entrance examination, but I have not been successfully transferred to this major. I have no interest in this major and have no intention to study. I spent almost all of my freshman and sophomore years in various departments. It was not until the end of sophomore year that I began to worry about my future direction.



Two, meet the customer

In fact, I did not know the existence of Pintek at first. It also happened that one of my Cousins used to be a student of Pingke. After knowing my situation, he recommended Pingke to me and consulted jack for a lot. Finally, he enrolled in the operation and maintenance class during the summer vacation and began to study. As for why I choose operation and maintenance, operation and maintenance is easier to accept for people like me who have no computer foundation. Of course, it is also cheaper than network classes.



Three, the relevant surface

Although my courses ended during the National Day holiday in the first semester of my junior year, I did not find an internship due to the large number of courses in my junior year. It was not until the middle of the second semester of my junior year that I began to apply for an internship. Back and forth, the interview hecky, thousands of lead, FULi, 4399, in the number, quantity. Finally, I only got the offer of Zhongdatong and Mobvista. Although the previous interview did not pass, but also as their own good experience, timely check loopholes to fill the gap, for the subsequent interview laid a certain foundation.



Mr Hickey

  2. Which direction is expected to develop in operation and maintenance

  3. How to check the number of network links

  4. How to View processes

  5. What Shell scripts do (account management scripts. Ps: Congratulations on the script cases taught in class)

Qian Led the overall question depth is not deep, the final interview did not pass the feeling that the internship time failed to reach their expectations. It requires four days a week, and the school is too far from their company.

R&f was promoted to be a platform operation and maintenance intern through Pingke

During the interview, he did not ask any technical questions. He also said that there was not much demand for operation and maintenance skills in the position. Instead, he asked a lot of questions about club activities and basically no technical questions. I didn’t pass the interview.

The interviewer was very kind and came in with my paper.

  2. Why not work in biology instead of operations?


Then I took the questions I did, Linux basic learning is good, compared to others interview people do very good paper. After that, he told me about some of his mistakes, and then he asked me about my club activities and hobbies. When I was talking about basketball, I learned that the interviewer was my classmate. Ha ha, meet or quite rare.


I continued the interview with a different interviewer

The rest of the questions are common ones.


After the interview, I went back to school. Just when I got back to the school gate, I received a phone call from hr girl informing me that I had passed the interview. Ask me when I can start. We talked about everything and we’re ready to start. On the day of entry, however, the two parties failed to agree on the internship time. (The other side stipulated that we should practice until graduation. I never went there.)


This time is already in July, basically should have a holiday holiday. Really a little panic, I didn’t pass the interview before, but I failed because of the internship time.

Finally, he showed me the customer request he had received in his mobile phone. The customer response service website was slow to enter the station and asked me what I thought about this problem.


Then change hr little sister to chat with me (this is easier.)


The whole interview process lasted for two hours, and the main time was spent on the technical questions in the first two rounds. I asked a lot of questions, but I answered the basic questions well. After the interview, I felt that I did not answer them well. But I’m glad I got through the interview.


Then I received a call from HR the next day to inform me that the interview had passed. I was lucky that I passed the interview of Mobvista. I had interviewed several companies before, and many of the questions I didn’t know were asked before, and I gradually made up the knowledge I didn’t know. The bumpy road to internship is finally over.



The last

Be careful to share a little. After these interviews, I also found that many questions in the interview were basically the same. I suggest that the children who have finished the Course should have a thorough understanding of the basic knowledge in class. If the basic knowledge is not good, they will suffer a great loss. Then is some details of the problem, more brush spell guest’s face, especially if there are past students interview with you of the same company, his face through the problem is to understand the point, basically ask those questions, not much. I wish you all get your favorite offer.
