Wang Hao spent about an hour and a half explaining the theoretical basis of 'Fourier transform to construct mathematical models'.

I took a ten-minute break in the middle of the break, and the rest of the time I was talking.

Most of the audience was listening.

The difficulty of the underlying logic mathematics is relatively low, and it does not involve any advanced mathematical concepts, as long as there is a certain foundation, there is no problem in keeping up.

Even so, at most one in five can keep up.

The technical staff of Abba Cloud R&D Center must have no problem with their ability level, but most of them are computer-related majors, and they have been exposed to computer-related content for a long time, and some mathematical foundations have long been forgotten.

Even if it does not involve advanced concepts, the minimum requirement is a bachelor's degree or above in professional mathematics, and it is already a lot to be able to understand one-fifth of them.

Fortunately, Wang Hao said at the beginning, "It's nothing to miss this part of the content, I don't know the underlying logic, and it doesn't affect the subsequent application." ”

The next step is to move on to the formal data construction.

This part is a direct application, which can almost be understood as giving a formula and copying it according to the formula.

Of course, the reality is much more complicated.

For the employees of the Abayun R&D Center, who have been dealing with programs for a long time, it is much easier to understand things at the application level with the "given formula" as the basis.

The vast majority of people can keep up.

Even if you don't listen well in the front, you can understand it when you follow in the back.

The latter part took a shorter time, and it took less than an hour to explain it all.

Wang Hao stood on the podium, half-turned to the screen, and stretched out his hand to make a demonstration gesture, "These are the overall framework of the Fourier transform to help establish the mathematical model." ”

"From the architecture, we can see that each part has open input ports, which can be adjusted at any time."

"Using this model, the analysis of massive data can be flexibly adjusted, and it can be used for data collection and analysis, classification, identification, etc., at the application level, you are all experts, I will not say more."

Wang Hao finally concluded, "Above, that's all, I feel like I've talked about it almost today, right?" ”

"I don't know, my report and explanation, whether it's 200,000, but it's all here, thank you!"

He said thank you and stopped.

The audience suddenly remembered the heated discussion, and many people also relaxed, shouting, "It's worth it!" Definitely worth it! ”

"Don't say 200,000, 500,000 is worth it!"

There were also people who didn't think it was a big deal, and shouted, "Dean Tang, you should give more money, 200,000 is too much, make up another 300,000!" ”

"Hahaha......"

A crowd laughed.

Tang Jianfeng's face darkened, he glanced back and said, "Okay, I'll deduct 300,000 yuan from you and supply Teacher Wang Hao." ”

The audience laughed even more enthusiastically.

End of report.

Wang Hao rested for a while, but continued to stand on the stage.

Feng Youlai came over and exchanged a few words with him, saying that he asked him to answer a few questions, and he was naturally indispensable.

Now for a question.

Each question is about the difficult point, and most of the questions are about the application of the back, and the mathematical foundation of the front is a little more difficult, but no one makes the question.

This is also normal.

Only the top technicians will care about the underlying mathematical logic, and most technicians know that logic is meaningless, and they pay more attention to the application level.

Wang Hao answered one by one.

Interestingly, there was also a technician in the middle who asked a question that had nothing to do with the content, and Wang Hao thought about it carefully and gave the answer.

This is definitely out of the ordinary.

If it was before, Wang Hao would definitely not be able to answer, but now it is different, a few hours of report has made him have a huge gain, a large number of program algorithm knowledge and ideas are full of ideas, he feels that he has become a 'top programmer'.

Of course, most of the knowledge and ideas are still related to the content of the report, and giving a speech does not allow him to really have a lot of knowledge and experience.

But it also feels like a big improvement.

Wang Hao answered eight questions in a row, and glanced at Feng Youlai, Feng Youlai was embarrassed to continue, and the employees in the audience were the same, it was almost nine o'clock, and many people should go home from work normally.

Feng Youlai came to the stage and said, "Today, we thank Mr. Wang Hao for the report, I personally think it is very exciting!" ”

"I've gained a lot!"

"I'm sure many of you are too. Here, on behalf of Eabayun R&D Center, I would like to thank Mr. Wang Hao! ”

"Thank you!"

Feng You said and held Wang Hao's hand.

After a polite exchange, it was announced that the presentation was over and everyone was free to leave.

At this time, it has passed nine o'clock, and there are still some employees who go back to work overtime, and will not go to rest until ten or eleven o'clock, not because they like to work overtime, but because they must hurry up to complete the work, and many jobs cannot be done at all.

This is the case for large Internet companies, where 9 to 9 in the morning and 10 in the morning and 10 to 10 are the norm at work.

Wang Hao did not leave either.

Tang Jianfeng and Feng Youlai enthusiastically took him to visit the R&D center, from the first floor to the second floor, from the second floor to the third floor, to the office, conference room, and the rest room of the staff, including the central computer room, database, etc.

The environment of the R&D center is really good.

Wang Hao followed a big circle, and finally arrived at the central office, which is also the largest office in the R&D center, where one-third of the seats are occupied, they are all working normally, and there are also a few idle people who come up.

They spun around together, and then sat down on the couch in the doorway.

Tang Jianfeng's expression became solemn, and he said, "Teacher Wang Hao, I listened to your report today, and it is indeed very good. I personally think it's a pity that a person as talented as you is just a lecturer at a university. ”

"I discussed it with Director Feng just now, and we both think that you are the talent that Abayun needs the most."

"If you are willing to come to Alibaba Cloud, I can call the shots and directly sign the P8 contract."

Wang Hao was about to open his mouth to refuse.

Feng Youlai followed by an explanation of the meaning of 'P8', which is equivalent to a 'senior technical expert' within the group, equivalent to a 'senior manager' in a management position, with an annual salary of 1.5 million yuan, and a maximum of 2.4 million yuan, and a certain amount of internal shares every year, which can be sold directly.

This is also Tang Jianfeng's greatest authority.

If it is a higher level, it is not something that Tang Jianfeng can decide, and it needs to be reviewed by the professional committee of the group.

With an annual salary of two million, one step to the sky!

Tang Jianfeng waited for Wang Hao's answer, he believed that the 'two million salary' started, and Wang Hao could not refuse at all.

The position of 'senior expert' is already the pinnacle of technical staff, and ordinary employees who have worked for several years can also reach P6, that is, the senior engineer level.

P8, arguably the highest level of technical staff.

Anything further up is not something that can be achieved through hard work, and only a very small number of employees can continue to be promoted.

If you enter Abayun and start directly at the P8 level, you can be promoted to P9 and P10 in the future, and truly become the 'head' programmer of Abayun, and every technical employee of P9 and P10 will not only get salary and shares, but they will also become very famous.

Through Feng Youlai's detailed explanation, Wang Hao also had a certain understanding, but his expression did not change, and he said directly, "Dean Tang, thank you, thank you." It's an affirmation of me, a trust in me. ”

"But, I'm sorry."

A lot of people have seen it.

Employees who can hear it from afar are incredible, and it's hard to imagine anyone turning down a job that starts at more than a million dollars a year.

Wang Hao said seriously, "I am not a teacher for money. This is my pursuit, my dream, and my favorite job. I love the profession of a teacher and want to pass on my knowledge to more people. ”

"A job with an annual salary of more than one million is indeed very tempting, but compared to dreams, hobbies, and pursuits, what is it?"

Wang Hao stood up after speaking.

He looked at the time, said sorry, and went back to the hotel.

Tang Jianfeng and Feng Youlai were still recalling what they had just said, and they were a little confused and found someone to send Wang Hao back.

When Wang Hao sat in the car, he couldn't help but exhale lightly.

Fortunately, let's go!

Most people will be defeated by money, not defeated just because the money is not enough, the job with an annual salary of two million is too tempting, even he was so moved just now.

In my previous life, I worked for 10 years in 996, and I was very tired and regretful.

But can 996 and 996 be the same? Can a part-time job be the same as a part-time job? A job with an annual salary of 2 million is the top person of the part-time job.

A world of difference, all right!

R&D center.

Tang Jianfeng sat still for a long time, he carefully thought about Wang Hao's refusal and firm tone.

He believed.

Otherwise, what else could be the reason?

Wang Hao definitely didn't lie, it was really because he loved his work as a teacher and hoped to pass on knowledge to more people that he would refuse Abayun's job with an annual salary of one million.

Then, Tang Jianfeng let out a long sigh.

He found that in terms of life pursuits, beliefs, dreams, etc., he was far from catching up with Wang Hao, who was only in his early twenties.

Childhood dreams......

Once a pursuit......

Steadfast ......

Everything was lost to money!

"Should I also quit my job, leave Abayun, get rid of the drag of money, and fulfill my dream of traveling the world with my wife and children?"

"Perhaps, go and do your own job?"

"What was my dream as a child? It seems to be ...... Participate in the bicycle race, or what~~"

Tang Jianfeng began to think philosophically about life.
