As a programmer who is about to apply for a job, facing a 2020 that may be very different from recent years, where will your job opportunities and outlets appear? In this new environment, should you choose a large company or a small company? How should veterans who have several years of work experience maintain and enhance their competitiveness and turn passive to active?
Judging from the current environment, the difficulty of successful job-hopping is much higher than in previous years. An obvious feeling: This year's interview, both on one side and on the other, tested the technical skills of Android programmers.
Recently I collected some basic questions and some selected interview questions from Ali and Tencent in 2020, and finally sorted out the technical points into a large and comprehensive "Android senior engineer" interview xmind (actually it took a lot more energy than expected ), including the knowledge context + branch details. Due to limited space, I will show you a rough picture in the form of pictures at the end of the article.
**So how can I pass the interview with a first-line Internet company? **I believe this is the doubt of many people. I hope that reading this article can give you some inspiration.
1. Broaden knowledge
Interest can't be stopped when it comes! Learn programming from the beginning, from ASP to ASP.net, JS, Winform, Java, C++, PHP, Python, all self-study!
But here I want to say that if you don't have one or two programming languages that you are familiar with, it is best not to teach yourself; getting started is the most difficult and time-consuming! If someone takes you to study, it can even save you 80% of your time. It is worthwhile to spend some money to study if you have this time to do bad things!
If you have the foundation, then self-study is relatively simple, and now there are a lot of materials for introductory materials (I need you to try to identify good or bad), especially the official Get Start is the best introductory textbook, but this requires you Learn English well, because the programming languages are all in English, and the original documents are all in English, except for the easy language.
I shake your face with radish and Chinese cabbage! Many people have this idea: Now that the pressure in life is so great, I am interested in money, and I am interested in whichever money is more!
In fact, many people now choose work because they look at money, and work is just a hobby.
But this may also be the reason why many people remain obscured at work throughout their lives.
If a person does something that he doesn’t like to do for a long time, it will be difficult to succeed, but if a person concentrates on doing something that he likes, it means that he has the quality and talent to do this kind of thing, and he does it happily. , Of course, it is easier to succeed. Do what you can do, don't let your mental emotions become an obstruction in your life, and be happy.
Being loyal to your own feelings and doing what you want to do is the source of a person's vitality. As a living animal, no matter subjectively and objectively, it is born to do things, and it is an indispensable part of life. The greatest happiness in life is not financial satisfaction, but being able to let go of what you really want to do, and enjoy doing it best. Doing things to the extreme, doing things purely and at ease is a high level of life. Excavate the subconscious mind to the maximum, find out exactly what you want to do. Go your own way, you can do anything as long as you want, not to wait for a clear and reasonable reason. Do what you want to do. In many cases, it is not as easy as you think, but you must strive for it with your heart.
2、IOT
This is what I really want to say.
What is IOT?
Wait a minute, let me search.
IoT is the abbreviation of Internet of Things. The literal translation is "Internet of Things", and the accurate translation should be "Internet of Things". The Internet of Things (Internet of Things) is also known as the sensor network. Briefly speaking, it is the extension of the Internet from people to things. "Internet of Things" (Internet of Things) refers to a huge network formed by combining various information sensing equipment, such as radio frequency identification devices, infrared sensors, global positioning systems, laser scanners and other devices with the Internet. The purpose is to connect all items to the network for easy identification and management.
The Internet of Things is connected to a router on the one hand, and a mobile phone on the other. In the future, the mobile phone will be a universal remote control that can control everything.
3. Mobile games
Nuggets hand travel industry guide:
1) hand travel industry tend to reason, "product is king" era
2) value into more diverse, mature pay-mode
3) hand travel out to sea, double complementary product and capital
4) end The four elements of the successful transplantation of Youdao Mobile Games
5) The future "socialization" of mobile games is indispensable
6) Giants lead the industry, and small companies make efforts
In addition, the idea of being a programmer is to do everything by yourself. Sometimes I want to develop a game for my child that is more helpful for him to learn.
4. Abundant learning resources
It should be said that it is the peak period of Android development, various learning resources are very rich, and all aspects have become very mature.
Makes the cost of learning greatly reduced. There are many free learning videos and articles for reference.
If you encounter any problems, you can basically find a solution by searching the Internet.
to sum up
Finally, in order to help you deeply understand the principles of Android-related knowledge points and interview-related knowledge, here are the 14 sets of real interview questions that I have collected and compiled by Tencent, ByteDance, Ali, Baidu and other 2020 interview questions . I have organized the technical points into Video and PDF (actually took a lot more effort than expected), including knowledge + many details.
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 do not research 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.
8%96%AA%EF%BC%81.md) has a direction reference for everyone.
