Early morning on March 16th.

Lu Zhou went back to the house last night and worked hard all night, constantly filling in some program logic of the advertising alliance.

It wasn't until early in the morning that Song Wenhui called Lu Zhou to sign the contract at Phaeton, and Lu Zhou got up and rode his bicycle to Phaeton.

The most important content of the contract is that Phaeton will invest in Dream Valley with the right to use ten servers for one year, holding 5% of the shares.

Lu Zhou, who was a little depressed, also carefully read the corresponding terms of the contract. The contract was also very satisfactory. There were no surprises, so Lu Zhou signed it directly.

After several contacts, Lu Zhou first felt that Song Wenhui was a boss with a long-term vision, but now he feels that he is a good partner.

Lu Zhou listed, "Have vision, have achievements, dare to fight and bet, be kind and not stick to trivial matters... If Menggu needs servers, it can be completely handed over to Phaeton. If in the future, I can use the cloud computing technology in my hands,

It would be even more perfect to have Phaeton under my command."

Lu Zhou had this in his mind, but it was not easy to implement it. After all, Phaeton was a company with nearly 30 million in server assets alone.

Immediately afterwards, Lu Zhou arrived at Zhuyuan 305. When he arrived at the door, he was surprised to see that 305 was crowded with people, including about twenty people.

Fang Qiang noticed Lu Zhou and hurried to Lu Zhou, "Brother Lu, good morning. These are the sophomores and juniors who are interested after I called on them yesterday. They want to come and take a look first."

"Hello, senior!"

Lu Zhou looked at so many people and sighed with emotion. It seemed that starting a business in Yixian was a good choice.

Yixian itself is a leading university in Guangnan, and most of the students in the School of Computer Science have a very solid foundation. After a period of training, they can quickly start working.

Compared with some experienced programmers who have worked for two or three years, although it takes time to train interns, the advantage is that they all have a blank sheet of paper, their minds are simpler than those in society, and they are more diligent and interested in learning.

Of course, employment costs are also much lower.

Lu Zhou cleared his throat and coughed. The students in 305 quickly fell silent and waited for Lu Zhou to speak.

"Hello fellow students, I am Lu Zhou, who graduated in 2008 with a degree in computer science. I am very happy to meet you all."

On the side, a junior student was about to applaud, but Lu Zhou pressed the button and continued, "Your senior Fang must have roughly introduced the specific situation to you. We currently need four interns here, so it is inevitable."

An interview and selection process is required.”

"Don't be discouraged if you don't pass. There is no merit in the interview selection here. It's just a matter of suitability. First of all, the most basic thing is to be able to complete major programming tasks independently. Those with acm experience are preferred. No way.

Students who can do this can leave first."

After listening to Lu Zhou's words, the surrounding students were silent for a while, and then became quiet again, which surprised Lu Zhou.

Fang Qiang, on the other hand, looked embarrassed. He leaned over and said in Lu Zhou's ear, "Brother Lu, these guys are basically candidates for the ACM team in the hospital, or former members."

Lu Zhou was also embarrassed, and then gave Fang Qiang a violent shudder, causing some laughter around him.

But immediately he was in a good mood, these juniors that Fang Qiang had found were all treasures.

Not to mention Yixian University's performance in the ACM competition, just being able to become a team member of the School of Computer Science means that they have passed the on-campus selection during their freshman and sophomore years and are almost among the students with outstanding abilities in the school.

So, Lu Zhou changed his words and made a joke, "Ahem, I just didn't understand the situation and made all the students laugh. If the ACM team members cannot complete the big homework, then other students will probably cry like ghosts and wolf howls."

All the junior students also smiled and felt that Lu Zhou was a lot more friendly.

"So, although it cannot be changed that Menggu only needs four interns at the moment, if we need to continue to expand enrollment in the future, we will give priority to the students who were not selected this time. I will introduce the question later and select the best among them. All students can take a moment

Wait a moment, if you need to go back to the dormitory to prepare, you can come back in fifteen minutes."

Lu Zhou called Fang Qiang. After thinking for a while, he came up with a question and asked Fang Qiang to print it out.

After fifteen minutes, everyone had a question in hand.

The topic is consistent with the advertising alliance program that will be done next, and is part of the business logic of the program.

Lu Zhou chose the CPI (pay per application installation) advertising model in the advertising alliance as the application scenario.

Students who need to answer questions should answer a few key points. One is the business logic of advertisers placing cpi ads in the advertiser's backend, followed by the SDK logic that developers access, and finally the data format of SDK callbacks.

In fact, Lu Zhou chose open-ended questions that could be answered in the form of text, diagrams, etc. What Lu Zhou wanted to see was to examine how they used dialectical analysis in areas they had never understood before.

Get the answer.

This is also the essence of programming. Language and technology are just means. As long as the thinking can keep up, there will always be means to achieve it.

Then, half an hour later, Fang Qiang collected twenty answer sheets.

Lu Zhou reviewed and approved each answer one by one, and each answer had its own uniqueness, which made it difficult for him to let go.

But after all, Menggu can't support so many people at the moment, so he can only make a difficult choice, "Okay, I have read your answer sheets and already have a candidate. But before announcing it, I will explain it to you first.

Question. Of course, this is not the only answer, it is for reference only."

“First of all, in terms of the logic of advertisers’ access, most students got the answer right.

Advertisers place ads, which involves access payment, background management of installation packages and advertising materials and other functional logic.

This is not only a common practice in the industry, but also the logic behind most customer management backends.

The students with the best answers designed the table structure of the database, and then explained the linking role of data in several modules in the subsequent developer module."

Lu Zhou continued, “As for the developer’s SDK logic, some students who have already been exposed to Android development have taken advantage of it.

But in essence, both the SDK and the data following the callback are traditional CS client and server communication models.

Therefore, whether they have been exposed to Android or not is not the key. The key is to examine the students’ flexible application of knowledge.”

After listening to Lu Zhou's words, I got up and asked, "Is this the question I just did? Why do I feel that it is different from what the senior said."

"Don't you see me kneeling and listening?"

...

Then, Lu Zhou cleared his throat again.

“Finally, what surprised me was that two students also mentioned a very critical point, which is the actual intention and scenario beyond the test questions.

They proposed to analyze the data and determine whether the advertiser's advertisement is suitable for the developer based on conditions such as region, mobile phone model and even age group.

And based on this point, it is discussed that the SDK can modularize the advertising program and replace the advertising according to the application situation."

"To put it simply, if the application developed by developer A has mostly young female users, then ads for cosmetics and clothing applications will be promoted to her; and if the application developed by developer B has mostly young single male users, then ads for it will be promoted to him.

Advertisements for chat apps..."

Hahaha, the students around me were also bursting with joy, but this is indeed the case.

Lu Zhoubian's in-depth explanation also gave many people a lot of understanding of the entire topic. They couldn't help but secretly sigh that the gap between themselves and their senior students is not small. After all, writing programs in an ivory tower is one thing, but when it comes to commercial use, it is one thing.

It's another story.

"This senior is quite interesting. He even explained it to us after it was over."

"Yeah. It's a pleasure to choose one. It's not a loss if you don't."

At the end of the explanation, Lu Zhou then announced the four selected people, and Lu Zhou also promised that the remaining people would be notified first in subsequent recruitments, and asked Fang Qiang to leave their phone numbers.
Chapter completed!
