Turn on the computer, turn on the nuggets, light a cigarette, also don’t know what to say.
I am a Java programmer or engineer. I graduated from Northeast Forestry University in the ice city of Harbin (no doubt you have never heard of it, but it is a 211 university). In fact, I didn’t participate in the autumn recruitment at all, because when I was in Beijing, all my resumes were approved in advance, and I only had one goal in my eyes at that time, which was to finish the autumn recruitment after the early approval.
I had an internship in 58 during the summer vacation. Rather than an internship, I wanted to expand my knowledge. The approval process in Beijing started early, so I resigned around August 15th (I also received the intention of becoming a full-time employee when I resigned), ready to fight against the wall.
Jingdong, Sina, Meituan, Baidu, Good future, Ali and advance approval were the only ones that gave me the opportunity to interview.
Ali’s side the interviewer is a p7, come up and I started Dui, he all the questions I answer basic it came up, but, unfortunately, in the end he said a words made me very sad, is not what I mean), try if ali is water, then I to try this at the expense of the water is too large, I dark for half a month after hang up, ali, Because I think my ability is in line with BAT, ALI failed me really puzzling.
I don’t know why many people are saying that luck is very important. I also admit that luck is very important, but luck alone is not useful. The harder you work, the luckier you will be. From the beginning of face sina, my autumn recruit began infinite harvest.

The interviewer said it was good, the core idea was right… 9. Have you ever been exposed to high concurrency? (No, they are all business driven technologies, not product driven technologies.) 10.

Then he introduced to me the various businesses and work of his department in the second interview (45+minutes) : This was the most uncomfortable interview in my opinion. The interviewer hardly asked about Java 1. Computer networks and operating systems bombarded the Tcp three-way handshake in turn, and the Tcp three-way handshake in turn, and the Tcp four-way handshake in turn, and the Tcp four-way handshake in turn, and the Tcp four-way handshake in turn.

Don’t you want to stay at 58? 14. During the q&A session (this is a relatively open session, so I will not record it), I had a brief chat and was told that if I passed, someone would contact me within two days (I thought the answer was not good, so I did not ask more questions).

I also determined my future development direction and forgot the other subjective questions. Can think of so much baidu’s three interviews is really a sword, each interview is in hot water, especially the second face. One week after the final interview, HR called to inform me that I had passed the interview. After completing the written test in 9.2, I received the email of employment intention. I was very happy. I was waiting in my room, and the HR who had arranged the interview was very kind and lovely, and patiently answered my questions. Thank you very much for 25+minutes of talking about Java basics. I can only remember the following questions. How to create object 2.Jsp nine implicit objects 3.

After these meetings, the owner of the building ended the autumn recruitment in the first week of September (because of the notice received through), think of their own dark days in Beijing, in order to find a job even eat a meal every day, from chaoyang to Haidian, in the run back to Haidian, such a rush now think or more meaningful.
Finally, the building Lord has his intention in his heart, and should also be the title of the word, I choose my own way, I kneel also want to finish.
