Preface
An Android developer friend told me about his interview experience. I went to iQiyi for an interview last week. Other questions were answered well. The interviewer asked a question about the Huffman algorithm but did not answer it. Later, the interviewer said clearly, We still want to find one that knows some algorithmic foundations.
If you have learned data structures and algorithms before, I suggest you to brush algorithm questions from time to time
Because from the perspective of interviews, current first-tier Internet companies such as BAT and TMD will more or less have a few algorithm questions, and for the corresponding graduates, the algorithm requirements are even higher! Here you can share the data structure algorithm questions with answers I collected.

End of sentence
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 problem with the logic.
However, senior engineers will consider a lot when they get the requirements, the feasibility of the technology? Does it help the existing business? 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 mobile development architecture project combat, etc.
Android cutting-edge technology; including componentization, hot upgrades and hot repairs, as well as 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?
It's 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 break through 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 for 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.
If you like it, please help forward and like it so that more people in need can see it. Thank you!
I have all the technical information contained in the above system outline. You can share it with friends in need for free!
