It has just signed not long after the US group, has recruited some time to settle down I feel pretty good, but now I think is not to be shared by the wave face. In fact, before the US group I was tempted into BAT tier companies, after all, most programmers have giant hearts dream. However, Ali's interview discourage me. What is a specific case, see below the surface and through the summary of it!
Note Note: The following questions + A inside the US group interview questions (with answers), as well as my personal review notes (including java programmers interview book, Android architecture design patterns + hot fixes + + plug-in process of keeping alive the study notes Video information architecture and performance tuning summarize the actual document) can be shared for free, there is need for a small partner directly ( click me ) to get Oh!
A hanging inside 01 (3 hang technical)
I graduated from has been three and a half, wanted to graduate into Ali, so it has been more than three years in preparation and learning, but also very concerned about the movements of the interview Ali, Ali, I get an interview before the interview is very confident, Ali heard do not care about education, many employees are college background, so as an ordinary graduate I have the courage, under this determination. When both sides before the interview, fairly well, so early on in barely disguised pleasure, thought capable of successfully won the offer, but was surprised to be pressed repeatedly third surface friction on the ground and had to gasp in admiration: indeed the first Internet companies.

02 US group developed post offer (the main research and development, two technical side + HR)
US group interview is more chance of a US group did not start on my interview list, the Ali I set myself a goal, but after interviewing Ali failure, have discouraged sinking for some time, but life still continues. Special thanks to her friends and classmates, classmates encouraged me out of the low life as soon as possible, and he helped me in the US group took the opportunity to push inside, adjusted the mentality to try again for a moment, to win the final 3 sides offer, now is the R & D one of the main team, the following share of US corporations face interview questions (including HR surface).

03 Review notes
I review the following notes with a total of five parts:
-
Architects build the base essential skills (Java)
-
Android Architecture Design Patterns
-
Plug-oriented
-
NDK Module Development
-
Performance Optimization
(1) architects to build the base essential skills (Java)
The manual skills of the finishing line of the Internet companies to build the knowledge base necessary skills, like generics, multithreading, reflection, JVM, Java IO, annotations, serialization and so on and so on.
(2) Android architecture design patterns
Android in the development process, the more popular development framework has been using the MVC framework mode. MVP is from the classic MVC model evolved, their basic ideas have in common places: Controller / Presenter responsible for logic processing, Model provides data, View is responsible for displaying. MVVM is a Model-View-ViewModel shorthand. It is essentially an improved version of MVC. MVP + MVVM + MVP study manual frame below
(3) plug of the core technology - Notes
（4）NDK模块开发
这份学习资料包括C/C++，jni，Linux基础等基础知识点，除此之外，音视频的编解码技术，流媒体协议，ffmpeg这些都是音视频开发必备技能也总结到了这份学习手册里，OpenCV/OpenGl/ 这些又是图像处理必备知识和人工智能相关的热点项目源码也都整理到这份手册里。
（5）性能优化
这份性能优化总结，包括代码书写规范，要求高性能高可用的代码，性能调优工具使用介绍，以及对已经成型的代码通过工具检查代码的问题，通过检查到的问题来指导我们进行代码的增删查改等。
写在最后
不要着急去实现自己的大厂梦，清晰自己的职业规划，朝着目标一点点努力，总有一天会取得成功。对于程序员来说，工作会一点点提升自己知识的深度和广度，但要记住的是，学习是不能落下的，因为时代在进步，技术在更新，只有更新了自己的知识库，才不会被行业所淘汰。
以上所整理的学习文档均可以分享给大家，共勉！
