Preface
During the interview season of Gold, September and Silver, I believe that everyone is in urgent need of an Android interview collection. Today, I have prepared the Android high-level interview collection that I have treasured for a long time, a super detailed Android interview essential knowledge points for everyone to learn!
Presumably every Android programmer has the determination to pursue a big factory, but what knowledge points do we need to master if we want to enter a big factory? Here, I have sorted out an overall knowledge structure for everyone. The whole includes Java, Android, algorithm, network, etc. I hope that after reading it, you can help you improve and organize your knowledge system. I wish everyone a smooth interview~~
At the end of the article, I will share with you the Android interview topics and answers I have compiled for reference~
Note that the entire article is a summary of the knowledge points and does not contain the answers. You need to read the source code more. Knowledge will be precious only if you explore and discover it yourself!
Instead of complaining, improve yourself
Compared with previous years, the difficulty of interviews has increased a lot. You said that with so many programmers now, your delivery company may have 300 people delivering with you, but they only recruit 5 people. What should I do? Resume PASS dropped a lot, and then the interview again PASS dropped a lot. From this point of view, the popular saying now: "Interview makes rockets, work screws" is still very reasonable. It is only to increase the difficulty of interviews to recruit the people you need from many people.
Many people complain that jobs are getting harder and harder to find now. Indeed, the Internet industry is not as easy to find a job as it used to be. I think a large part of the reason is that too many half-way programmers have been trained in the current training courses. The training courses have lured many people into this circle with the title of guaranteeing your high-paying employment. I am not biased against people who are halfway through the family, but the fact is that some people who come out of the training courses are really not competent for many jobs. One is that most of the training courses are very motivated. To put it bluntly, many training courses are for collecting money; the second is that the foundation of a half-way renunciation must be that there is no good person who has not studied computer knowledge in a big way. This has resulted in many training courses. It is difficult for people born to move forward; third, the Internet industry does have a partial preference for young people. After all, college students who have just graduated are relatively cheap, but the Internet industry does not eat youth.
Therefore, whether it is a birth in a training course, a fresh graduate or a small partner who has been working for a few years, you must have a clear understanding of yourself, figure out what you lack, and figure out your own advantages (why the company should recruit you). After you know your shortcomings, you must work hard!
The Internet industry is actually quite fair. Although your academic qualifications will be used as a reference during the interview, if your abilities are really good and your resume is really rich, interviewers will still appreciate such candidates.
How to improve personal hard power?
The personal hard power I am talking about here refers more to personal professional abilities, such as the ability to build high-quality websites or the mastery of professional knowledge.
I think whether for a novice or a veteran, the most important thing to improve your personal hard power is to continuously study and practice the theory. It is best to put the theory into practice in a specific project.
A suggestion to students who are still in school: If possible, try to participate in some competitions. Maybe your skills are not very good. You still hesitate in your heart whether you have the ability to participate in the competition, but I still recommend you to go. try it.
why? The preparation time for a competition is 5 to 6 months if it is longer, and 2 to 3 months if it is shorter. Before participating in this competition, you may not have actually applied many of the techniques used in the competition, or even listened to it. But these few months should be enough for you to study. If your attitude is good and your self-learning ability is not bad, there is generally no problem.
In the end, you may not get an excellent ranking, but I think the experience of participating in the competition is the most helpful to you. If you will participate in other competitions later, I think you will do better and better.
In addition to competitions, actual projects are also very important for improving and exercising one's personal abilities.
Practice more and apply what you have learned to actual projects. Many people have come to me complaining that there is no actual project for them to do. Below I will introduce several ways that you can have project experience. Project experience is very important for the improvement of technical skills and interviews.
Finally, take a look at the "Android Framework Architecture (Advanced UI+FrameWork Source Code)" mind map of all the knowledge points needed for learning. All the content of the following knowledge points are included in the study notes just now! Part of it has been shown in the article! If you are worried about how to learn or want to improve the efficiency of learning this knowledge, then this study note is definitely your secret weapon!
