Will I definitely learn some cool skills if I go to a big bat company?

A classmate said that he went to Alipay for an interview on mobile development. The interviewer asked him a few low-level questions about iOS, but he couldn’t answer them. The interviewer said that he could learn these technical questions by coming to Alipay, and there were a lot of technical documents internally... People who like technology will inevitably feel itchy and excited when they hear this.

This kind of rhetoric is just to fool people without experience. Since Alipay has so much technical information, are all the technical team members experts? How many mobile development experts have been trained with these materials? If you go there, are you sure you will become a technical expert?

There is more technical information inside Alipay than on the entire Internet? And how many people have become technical experts?

For example, if Alipay's mobile technology is really great, why hasn't the crash of the App on iOS 9 been resolved? Are the mobile development teams of hundreds of people busy studying technology and not solving problems? No, it is the working mechanism of large companies that determines that they cannot become so-called great people. All their time and resources are consumed by internal processes and complex mechanisms. They are busy with meetings, so they have no time to solve problems, and naturally they have no time and opportunity to become great people.

Engineers should not have any technical illusions about the technology of big companies. If you want to join a company, it is because of their technology. You should think carefully about it. What are the possibilities of you becoming a technical expert if you join a big company?

This possibility is almost zero. As the period of explosive growth becomes history, there will be no more technical talents emerging in large companies. If you can still see some talented people sharing their experiences, it is because they are already very talented and now they are even more proud of the halo of large companies.

An important prerequisite for becoming a technical expert is opportunity. For example, if you have not experienced the rapid growth of Taobao, you will not be able to truly master how to solve the problem of high concurrency and the problem of flash sales. The general technical direction is easy to understand, but if you do not have the opportunity to practice, it is useless.

One factor that makes a person a technical genius is continuous learning. Nowadays, you can find any development technology you want to learn on the Internet. How deeply you can master it varies a lot. The reason why geniuses are geniuses is that they can continue to learn, so they can enjoy the benefits of "compound interest".

Don't think that you will have all kinds of training lectures when you join a big company. Not to mention that those lectures are actually very shallow. Even if you listen to lectures by great people every day, most people will not become great people. Why? People are reluctant to improve themselves. They are too lazy. If you don't believe it, think back to when you were in school, you had classes every day. Who learned the basic skills well?

Similarly, not all engineers from BAT are experts. Many are at best mediocre. If you remove the halo of a big company, their own value is very little. This should be an objective fact, although many teams still believe in this.

Some startup teams like to write: core members come from BAT and other companies. In fact, this basically tells others that our team members can't do specific things, so we still need to work.
