Mainly talk about personal experience, hoping to give some effective information to the interviewing partners. Everyone must cheer~
basic situation
Let me talk about my basic personal situation first, majoring in computer science and technology. Mainly learn Android development, so the job positions are all Android development engineers. I voted for Zhihu and internally pushed Ali Mogujie, Tencent, Baidu Netease. Tencent and Baidu have not received any interviews. I know that Skype interviews, Mogujie Ali phone interviews, and NetEase live. Zhihu was rejected on the second side, Mogujie Ali was rejected on one side, Netease on the other side, and then spare tires. I was notified a few days ago and received the offer. I have sorted out the questions I have been asked, and now share them with you. In addition, the information I have sorted out will also be sent to you, hoping to help all job-seeking partners.

In 2013, the author switched from Java development to Android development. He has been in a small factory, and he has also been to a large factory such as Huawei and OPPO. In April of 2018, he has been in Ali until now.
I have participated in many interviews and interviewed many people as an interviewer. I know that most junior and intermediate Android engineers want to improve their skills. They often grow up on their own. The unsystematic learning effect is inefficient and long, and it is easy to encounter the ceiling technology stagnation!
I have compiled a list of the most systematic Android development mainstream technologies at the Ali P7 level, which is especially suitable for in-depth learning and improvement of small partners with more than 3-5 years of experience.
Mainly include Ali, and the mainstream architecture technology of ByteDance, Tencent, Huawei, Xiaomi, and other first-line Internet companies. If you want to learn Android development in depth and become a qualified senior engineer, you can bookmark these advanced Android technology selections
I have collected and sorted out the interview questions of Alibaba, Tencent, ByteDance, Huawei, Xiaomi and other companies in the past few years, and sorted out the interview requirements and technical points into a large and comprehensive "Android architect" interview Xmind (in fact Expected to spend a lot of effort), including the knowledge context + branch details.
Java language and principles;
big factory, small factory. Android interview first see if you are familiar with the Java language
Advanced UI and custom view;
custom view, the basic skills of Android development.
Performance tuning;
data structure algorithms, design patterns. All of the key foundations and key points need to be skilled.
NDK development;
future direction, high salary is bound to be.
Cutting-edge technology;
componentization, hot upgrade, hot repair, frame design
There are a lot of materials for learning Android on the Internet, but if the knowledge learned is not structured, and when you encounter problems, you just taste it and stop studying it in depth, then it is difficult to achieve real technological improvement. I hope that this systematic technical system will provide you with a direction reference.
When I was building these technical frameworks, I also sorted out the advanced advanced tutorials of the system, which will be much better than my own fragmented learning effect, visible on GitHub; "Android Architecture Video + Study Notes"
Of course, it is not easy to learn and master these abilities in depth. Everyone knows how to learn and what work intensity is as a programmer, but no matter how busy the work is, I have to spare 2 hours a week to study.

Within half a year, you will be able to see the changes!
