Chapter 21 Damn, this young man! Arrived inside the house. He first nodded and gestured to the three interviewers opposite him, then quickly looked around. The entire reception room was extremely tidy and clean, and fortunately there were no childish things like paper balls and brooms. The two interviewers in front were sitting in a row. There was a person sitting in the corner. There was a seat in the middle, which should be his seat. There was an extra-large whiteboard behind him. Chen Mo walked straight to the seat in the middle and sat down with his legs spread wide, his back pressed against the back of the chair. He did not sit upright like the others. Because Chen Mo always felt that that posture looked like he was touching half of his buttocks and secretly opening a gap to let out a silent fart. Attitude is worthless in the face of strength! After sitting down, Chen Mo raised his eyes and observed the other three people. The person in the middle was very familiar. It was Lei, the leader of Xiaomi, the monkey trainer, the UP host of the ghost animal area, and the marketing master, Jun, who often appeared in the news and video reports in his previous life. Oh, and now we have to add the billionaire car boy to the mix. However, this was the first time Chen Mo saw Lei Jun breathing heavily. He looked much younger than he remembered, and had some of the qualities of a science and engineering man. The person next to Lei Jun has a broad forehead, wears narrow-rimmed glasses, has a strong hairstyle, and looks very gentle. Chen Mo can feel the same technology fanaticism in the other person. It should be Lin Bin.
As for the third person sitting in the corner, he has an ordinary build and appearance, and I don’t know him, so I’ll skip over him. While Chen Mo was looking at the three people, the other party was also looking at him. Youth is their most intuitive feeling about Chen Mo, but strangely, they did not feel that he had that kind of youthful spirit. Instead, he had a sense of leisure and ease that went with the flow. The three of them have been in the business world for a long time and have some aura to a certain extent, but the other party was not affected at all, unlike the others who were cautious and respectful. At least from this point of view, the three of them had a very good impression of Chen Mochu. After Guan Yingzhi came in and sat down next to Lei Jun, he made an opening statement, "Hello, Mr. Chen Mo. First of all, let me introduce you. On my left is Lei Jun, the chairman of Xiaomi, and next to me is Lin Bin, the general manager who is currently in charge of the company's overall technology. After discussion, we feel that the written test you did this morning has reached the level of our Xiaomi technical manager, and Xiaomi happens to be in need of a technical manager, so we would like to ask you first whether you are interested in the position of Xiaomi technical manager. " Since Liu Qin was just a bystander, Lei Jun did not greet him in advance, and Guan Yingzhi did not introduce him either. Seeing Chen Mo nod, Guan Yingzhi continued, "Next, let's start the interview." After saying this, Guan Yingzhi handed the right to speak to the two CEOs next to him. Lin Bin looked at Lei Jun, then spoke first, "Then I'll go first." Chen Mo thought that Lin Bin would have an opening speech or something, but he didn't expect that the old guy would be so unsportsmanlike and just flash and attack close to Chen Bin with his ultimate. "Chen Mo, I have five questions for you to answer. First, what is 2 to the 16th power? Second, what are the advantages and disadvantages of PHP and JAVA, and what are the differences between the two? Third, please talk about the cause of the overselling problem and the corresponding solution. Fourth, Android is now open source, please comment on the underlying architecture based on your own understanding." Lin Bin spoke very quickly, with almost no pause between each question, as if he did it on purpose. On Chen Mo's side, there was no panic on his face. He just thought for a moment and then began to answer. Chen Mo's answer was not as fast and aggressive as Lin Bin's, but steady, powerful and clear. The first question was not difficult, and it tested his sensitivity to numbers. Chen Mo directly gave the answer 65535, which means in computers that it represents the maximum value of a 16-bit binary number, which is 2 to the 16th power minus 1. So he did not calculate it, but this value is often related to the memory address, and he remembered it after encountering the problem many times in his previous work. The second question can be answered as long as you know a little bit of programming, but the same question will be answered in different depths by people of different levels. Chen Mo briefly explained it from the aspects of application scenarios, ease of use, middleware, source code, etc. Chen Mo even has his own understanding of individual functions in the source code, and thinks that slight changes will produce better results.
The third and fourth questions were also answered quickly, and the answers were perfect. Lin Bin and Lei Jun nodded repeatedly, and a smile appeared on their originally serious faces. The last question was an architecture design question. Chen Mo stood up and walked to the huge whiteboard at the back. He picked up a pen and started writing and drawing on it. Soon he occupied half of the whiteboard, explaining his ideas as he wrote. Lin Bin would ask about a certain detail from time to time, and Chen Mo would answer. Gradually, the two of them went from asking questions to having a discussion. Later, when Chen Mo was so excited about writing, he directly picked up his pen and tore out the code implementation, which was extremely vigorous. In just a few minutes, half of the blackboard was occupied by densely packed codes. After Chen Mo's continuous explanation, Lin Bin felt that the execution rate was extremely high and nodded frequently. This is like taking a bunch of beverage bottles and junk with your bare hands and tinkering with them to make a flying device that can achieve three-stage separation energy like a rocket. It's just outrageous. At this point, Lin Bin no longer doubted the other party's skills, but just envied his age. Then he asked some more questions about the other party's written test questions, such as why did you write it like that at the time, and when you took the written test for this question, you only wrote the key points. Can you explain it in more detail? Chen Mo gave an explanation. When Lin Bin asked about the last question about Double Eleven in the written test, unexpectedly, the two had a disagreement on the details of a design module and argued endlessly with each sticking to their own opinions. When Lei Jun heard the two, he said, "I have never seen this kind of design at Google. How can you, with just a bachelor's degree, say this is right? It's simply unrealistic." "What's wrong with undergraduate studies? Did your undergraduate degree make you rich? Didn't you also graduate from undergraduate studies? That's because you are ignorant and you are surprised by what you have seen. Existence is reasonable. Facts have proved that there is no problem with the design of this piece." "I don't agree with your design and run?" "Just run away? No, I didn't even pass the interview, why should I design? How can you cheat like you? You old man are very cunning, I almost got tricked by you." Chen Mo deliberately made a frightened expression as if he had been fooled. Lei Jun, who was standing next to him, listened with great interest at first, treating the interview as a technical discussion. This scene was rare, and it was a great enjoyment in life to have such an experience. But gradually he felt that something was not right. If he let the two of them continue talking, it would not be a meeting and they might even start a fight. Seeing this situation, Lei Jun quickly interrupted the two people who were in a state of technological frenzy, slammed on the brakes, and brought the topic back to the topic. Guan Yingzhi sat next to Lei Jun, feeling like he was walking on thin ice and having a thorn in his back. Although she didn't understand these technologies, she could feel the atmosphere of tit-for-tat. She was able to fight Mr. Bin, who used to be an executive at top companies like Google and Microsoft, for 300 rounds and not lose the upper hand. It is absolutely impossible that Chen Mo works for a small company called Shanghe as written in his resume. Could it be that this technical genius just made up his resume and deliberately concealed his shortcomings to test Xiaomi's sincerity in recruiting? He looks so young, and geniuses are always attracted to each other. Could it be that he is here for Mr. Lei, who also became famous at a young age? Thinking of this, Guan Yingzhi looked at Chen Mo again with awe and a hint of curiosity in his eyes. This guy must be a big shot from some world-class giant, because he is so low-key due to the non-compete agreement. Microsoft and Google are definitely not, because Mr. Bin will definitely know them. Besides these two, could it be Amazon, Nokia or Samsung? Which one is it? (End of this chapter)
