Rebirth 2010: I taught Mr. Lei how to make a mobile phone

Chapter 17 Is he really a genius? (Please read on)

[Facebook is currently one of the largest social media platforms in the world, with over 4 million users and over 1 million people online at the same time. Please design an architecture solution that supports a platform with hundreds of millions of users? (Technology is not limited, you can draw a picture)]

[If you are a manager and you have an employee who is very capable but does not fit in with his colleagues and is somewhat eccentric, how would you handle this? Please explain the reasons for this decision.]

【On November 11 last year, Taobao's "Double Eleven" shopping festival had a transaction volume of 11 million. If you are an architect, what common problems will arise in this instantaneous high-concurrency scenario? Please explain from the aspects of design architecture, prevention of emergencies and emergency plans.】

Chen Mo thought that the difficulty of the written test questions was about the level of mid-level and senior software engineers, but this set of written test questions was obviously beyond the model, and it was estimated that they could be used as written test questions for senior architects and technical managers.

The complexity of this set of written test questions was somewhat beyond Chen Mo's expectations.
Guan Yingzhi felt secretly happy when he saw the other person was in a daze due to surprise.

She had just urgently printed out a copy of this written test question, with the purpose of making this man named Chen Mo give up when he saw the difficulty.

Afterwards, he lost interest in watching and walked towards his workstation, thinking that the other person would probably be gone by the time the papers were collected.

This way, it's good for everyone, and everyone can save face, avoiding noise and affecting other interviewees.

As a veteran in the workplace, Chen Mo knew the other party's intentions.

But it’s good this way, it’s more interesting with some intensity. Otherwise, it would be boring to always do those 1+1=2 questions.

Then Chen Mo looked at the time on the wall. There were 36 minutes left, so he had to hurry.

I went through the questions again from beginning to end. It was obviously unrealistic to finish all of them, so I could only pick the key and challenging questions to answer, and only answer the key points so that the interviewer could see my thinking on these questions.

I first spent 3 minutes reading the entire test paper, circling and drawing on the test paper with a pen, marking the questions that needed to be answered. At the same time, I had a general idea in my mind.

Finally, he picked up the pen and began to answer the questions, still starting from the last big question and working his way up with a focused expression.

Be as urgent as grass and race against time.

However, this scene just now did attract the attention of the interviewees around. After all, a guy who was interviewing for a software engineer position had finished most of the mobile engineer test paper with great difficulty, and then was notified that he had made mistakes.

You have to know that different fields have different meanings. Although they are all engineers, there are differences between engineers. It is not an exaggeration to say that those who develop websites and those who make apps have to cross at least half a mountain. It seems that what this guy said just now was still modest. He doesn't look like he knows anything at all.

In particular, the buddy next to Chen Mo discovered that the other party got two more test papers than them. What was going on?
And looking at this guy's aggressive and tiger-like posture, it's a bit scary no matter whether it's true or not.

Sun Ziwei, who was far away, heard the noise and looked towards Chen Mo worriedly. He didn't know the specific situation because the screen at the workstation in the distance blocked his view, but at least the worst-case scenario of being kicked out on the spot did not happen. He felt relieved and turned around to continue working on the written test that was giving him a headache.

Programmers often complain that interviews are like building rockets, while jobs are like tightening screws, and there is a reason for that.

Whether he could screw screws after joining Xiaomi is another matter. At least he had to build rockets. The written test in front of him was not only difficult but also complicated. There were not only JAVA, which he was good at, but also C and PHP questions. Fortunately, he had been exposed to some of them in college and practiced when taking private jobs. He had some basic knowledge and could only bite the bullet and write it.

It is estimated that Chen Mo is in danger, because he knows that this guy is not like him who can apply what he has learned to other areas and is not an all-round technical talent. This guy has never learned C and PHP, and only knows JAVA.

Next to Sun Ziwei was a spirited young man who looked up from time to time at the huge machine next to him. The workstation, which seemed somewhat spacious, made him feel a little crowded.

I couldn't help but secretly gasp. My goodness, whose programmer looks like a heavy-armored soldier? Could this big guy be a fitness guy as a main job and a programmer as a side job? Actually, this guy guessed it right, but he just got the order wrong.

As everyone's thoughts were in a mess, the only sound they could hear was the sound of pen touching paper.

As time passed, some people chose to hand in their papers early. Sun Ziwei looked up and saw that they were, as expected, geniuses from famous schools or big companies.

He stood up and looked over. Chen Mo was still writing furiously at his desk.

This made Sun Ziwei a little confused. He had almost finished answering the questions, but why was this kid still not done? Was the amount of questions so huge?
Time flies, and it is noon. Guan Yingzhi returns here on time and starts collecting the papers.

When she came to Chen Mo's side, she found that the boy was still at his workstation. She couldn't help but feel a little dissatisfied with this man's lack of appreciation, which made her frown. Then she picked up the interview questions, took a rough look at them, and wrote most of them.

It seems that this kid is determined not to give up and is quite stubborn. Wait until I let my technical classmates criticize it, and then I will convince you.

Guan Yingzhi didn't say anything and put Chen Mo's previous and current written test papers together.

After sorting out all the written test questions and resumes, he said to everyone, "Thank you for your cooperation. We will review these written test questions. It is now 11:2 and I will announce the results here on time at pm. You can go eat and rest nearby first."

Guan Yingzhi came to the technical department with a stack of written test questions and said, "Here comes another batch. Can you guys help me screen them?"

After saying that, she returned to the front desk to do her own thing.

Ten minutes later, a technical colleague came over with a written test paper.
"Sister Xiaoguan, this paper is beyond our capabilities. It belongs to the level of a technical manager."

"You just need to take a rough look. If you didn't answer the previous questions, you can check whether your answers to the other questions are reliable. I guess you are just filling in the gaps."

The technical colleague looked a little embarrassed. "Well, it's mainly because you have to answer all the questions correctly. And there are a few questions here that I'm still unsure of after discussing with several colleagues. President Li is on a business trip. Do you want to let President Bin take a look?"

The Mr. Bin mentioned by the other party is named Lin Bin. He is one of the co-founders of Xiaomi, the former R&D director of Microsoft, and the former vice president of Google China Academy of Engineering. He is the second most important person in Xiaomi after Mr. Lei.

"Mr. Bin?" Guan Yingzhi originally wanted to ask colleagues in the technical department to review it and give a conclusion so that the other party would give up. She didn't expect to get such a result, which surprised her.

"Are you sure you need Mr. Bin to take a look?" Out of caution, she confirmed with the other party again, and the latter nodded without hesitation.

"Okay, give it to me first." Is he really a genius?

Considering that the other person is so young, it feels unreasonable.

Guan Yingzhi took Chen Mo's resume and written test questions and came to the door of Lin Bin's office.

After hesitating for a long time, he still knocked.
