Learning ability, especially self-learning ability. When do you see those famous program masters asking questions like "what books to read when learning XX, how to quickly learn XXX, and what code recommendations for learning XXX", they want to learn What can I find relevant information soon. The industry is developing too fast, and the speed of technology obsolescence is also fast. If you don't learn new things for three years, you may be out of date.
Practical ability is all about reading books and reading materials. When others are still entangled in what books to read and what the words in the book mean, some people's hundreds or thousands of lines of code can already run.
Patience and perseverance are important to be a programmer. It is quite enjoyable to write your favorite code, but there are still a lot of boring and boring things in program development anyway. You must be able to persevere and grit your teeth to finish.
Ability to express, able to speak clearly and fluently of one's thoughts in a large public, so that people can understand.
What about technology? Technology is not important. With the above-mentioned capabilities, what technology is needed in the market will soon be mastered.
Finally, let’s talk about wages and remember two sentences:
Salary is not the boss’s return to your past contributions but the expectations of your future contributions.
The current boss cannot give you a satisfactory salary, the next boss will only.
Generally, the job requirements of the official website or Liepin.com are written very clearly, and you can check whether they are competent or not. Even if you don't succeed, you can find your own shortcomings and make up for it.
OPPO's larger factories have seen a lot of Java language, source code layer, project experience, etc. Need to have a more systematic knowledge system, understand the principles and write source code by yourself, etc.
Here is a brief share of my interview experience with you, I hope to give those friends who are ready to change jobs a reference

8. What do you think of the mentor's patent work?
9. Can you ask me a question?
The sharing is over here, you can gain mainly one direction. It is impossible to say that you have been developing for several years, and now you have not even studied the architecture and the underlying source code. After reading a few other people's experiences, you can go to interviews for senior positions.
At last
All in all, the Android development industry is changing too fast. As a technician, you must maintain a lifelong learning attitude and let learning become your core competitiveness. The so-called "live to learn and learn" can only keep up with continuous learning and continuous improvement. The pace of the industry will not be eliminated by the times.
Here I share a collection of dozens of interview questions from Tencent, Toutiao, Ali, Meituan and other companies related to the above-mentioned technical system diagram. The technical points are organized into videos and PDFs (actually more than expected. A lot of energy), including knowledge + many details. Due to limited space, I will show you a part in the form of pictures. A friend in need can private letter I [DATA] or click here to receive a free
There are also advanced architecture technology advanced brain maps, Android development interview topic materials, advanced advanced architecture materials to help you learn to improve the advanced level, and save everyone's time to search for materials on the Internet to learn, and you can also share with friends around you to learn together. Receiving address: Android learning PDF + architecture video + latest interview document + source code notes
