Dachang offer is the pursuit of every technical person?
I think the dream of every programmer is probably to find an offer from a major manufacturer. I think this is normal. This is not our after-dinner talk but the pursuit of every technical person. The technical atmosphere and technical standards of Ali, Tencent, Meituan, ByteDance, JD, etc. are still significantly better than those of some entrepreneurial companies/small companies. If you can practice in such a company for several years, I believe that you can The improvement is still very large. But not everyone can enter the big factory, which often depends on our ability, education background, interview performance and other factors.
Now when you interview a big company, you say that you don't have the necessary knowledge for interviews with big companies such as Android Jetpack, coroutines, Jetpack Compose, Flutter, etc. However, if you have really entered a big factory, you may not need this knowledge for several years, so you should write CRUD honestly.

to sum up
First of all, I feel that my own foundation is not enough. Major manufacturers seem to like to ask about these underlying principles.
Another part of the reason is that the information has not been read. On the one hand, I can easily deal with it after a few days before the test with that information (I still want to thank the information, really good), so I feel good about myself. The information didn't go into further.
The previous preparation only involved Java, Android, computing networks, data structures and algorithms, and it was difficult for interviewers to investigate other basic courses.
The next step is to check the omissions and fill in the vacancies and conduct targeted reviews.
In the end, the set of materials must be read all this time, it is really too comprehensive, and all the knowledge points are covered, and almost all the knowledge points I encountered in the interview are there! Here is also free to share with you, I hope you will not make the same mistakes as me! ! ! Be sure to finish it!
