Continue to update and improve the answer - Recently, the Android friends around the blogger changed their pits and received interview invitations from major companies such as BAT, and came back to chat. The blogger recorded some useful interview questions that major companies must ask. I hope it will be helpful for your study, work, and interview. (The blogger will continue to collect and update these interview questions). The blogger will filter the interview questions for sharing and submission. Thanks again for sharing the interview questions, friends and readers
When it comes to senior engineers, everyone's first impression is naturally that they have rich work experience and strong skills.
Note that this is about work experience, not working hours. Some people work on projects steadily, thinking about learning more new technologies in their spare time, insisting on reading, writing blog summaries seriously, practicing more, plus their own savvy and not bad, they can have two or three years. With 3 or 5 years of work experience, it is natural to grow into a senior engineer in the company. And some people mix up their lives, do projects that are easy to pass, play games in their spare time, and chase dramas. Maybe you have been working in the company for 10 years and look conscientious, but you don’t have higher requirements for yourself. Even if these people have 10 years of working hours, they can only stop there.
The junior engineer will start to do it directly when he gets the requirements, and then do it and find that there is a problem, either the technology cannot be realized, or there is a logic problem.
However, senior engineers will consider a lot when they get the requirements, the feasibility of the technology? Does it help existing businesses? The impact on the existing technology architecture? How scalable is it? Wait...then the design coding stage will be carried out later.
And now with the popularity of cross-platform development, hybrid development, and front-end development, the technologies that Android developers need to learn and master are also increasing.
Through exchanges and discussions with friends in some industries, and refer to the current interview requirements of major factories. We spent almost a month sorting out all the knowledge systems that this Android senior engineer needs to master. You can see how much you have mastered.
Hybrid development, WeChat applet. All have to be learned and proficient;
These are the cores of Android related technologies, as well as advanced Java
Some techniques necessary for advanced advanced. Like the actual combat of mobile development architecture projects, etc.
Android cutting-edge technology; including componentization, hot upgrade and hot repair, and detailed technical systems of various architectures and frameworks
The above is the technical system we have compiled for Android senior engineers to master. Many friends may think that many technologies can be achieved by themselves, but some new technologies are not clear. There should be no big problem.
And this is precisely the problem! Why other senior engineers can exceed 300,000 years, but you only have a few hundred thousand?
Just because you only need to add what you think you need, but you don't know what the company needs. This is particularly easy to cause gaps. Because your technical system is not systematic, it is fragmented and scattered. So why do you exceed 300,000 annual salary?
These words of mine are relatively straightforward and may poke some people's glass hearts, but I know it will definitely have a wake-up effect on some people. As long as someone finds a direction based on my advanced system outline and these words, and takes action to improve themselves, they will work harder to succeed. Then what I did all made sense.
Finally, in order to help everyone deeply understand the principles of Android-related knowledge points and interview-related knowledge, here are the 24 sets of Tencent, ByteDance, Ali, and Baidu interview questions that I have collected and compiled. I will organize the technical points into the video and PDF (in fact, than expected to spend a lot of time), including knowledge context + many details .
There are also advanced architecture technology advanced mind maps, and Android development interview special materials to help you learn and improve, and save everyone's time to search for information on the Internet to learn, and you can also share with friends around you to learn together.

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.
