Three years of experience in Android development interview (I regret that I didn't get n+1, Android bottom development tutorial

When someone successfully passes the interview of a large factory , There will always be people who think this is better luck , But they didn't know how much pain and grievances the other party had suffered before , How much effort have you made to break through these difficulties step by step . Because of their efforts , At the right time and place , With the results of their own efforts to firmly seize their own opportunities . It can be said to be luck when encountering opportunities , Whether you can grasp it depends on your own strength .

No more nonsense , To put it bluntly, my recent interview experience . There are many companies that I have submitted my resume , Basically received the invitation of interview notice , There is a resume that makes my blood boil , There are also experiences that let me feel helpless , So I recorded all these experiences , It's worth thinking about , I interviewed so many companies , If nothing is left in the end , So much time is wasted . At least for me, sort out and summarize some good and bad experiences , In the end, I'm sure I can wait for the answer I want . I hope these can help everyone who wants to change jobs .

Leaving reason

When the company laid off staff, our boss said to me ： You stay and work hard , No matter how the company divides its shares 、 option 、 Certainly not without you . At that time, I trusted the boss , It's a pleasure to work with the boss .

But I didn't expect that after the layoffs , There is great turbulence within the company , Main business line from client A The business line is transferred to B Business . My main responsibility is A Client Architecture , So I was idle .B The business line is busy , There's no time for me to do something about the architecture . So I check all kinds of learning documents in my brain every day , Add knowledge points and energy .

After a few days , I regret that I didn't have that N+1 Leave , I feel cheated by the boss . Because what happens later is that I won't talk about it for the time being . It's just that I've had a little experience , I can't see some big trends , Or old birds are smart , Take money away , Then change a new job , I'm not at ease .

It wasn't long before I left , Started my interview trip ~

I rested at home for about a week , Give yourself a simple relax . After the rest, I began to submit my resume （ The world is so big , I want to see it ）. This opportunity is different from the past , I decided to prepare well first , And then start sending your resume , Mainly through friends' internal push ,Boss Direct employment .

This time, I will divide all companies into three categories ：

1.A class ： BAT company , Very reliable , All kinds of treatment are very generous

2.B class ： Some famous Internet companies （ Basically all in C Above the wheel ）, It's basically reliable , There should be no shortage of

3.C class ： It's the companies that are hiring , It's not famous , Although there is a lot of money, there are many things . I don't know if it depends , Only chance

Foundation is very important

I always felt engaged in Android Development work has been going on for several years , There should be no problem with the basic questions in the interview . Officially because of their arrogant self-confidence , Cause oneself to always hit a wall , Especially when you encounter many basic questions , I was embarrassed and didn't know how to answer ？ Another situation is , Remember some questions accurately before the interview , But when I answer , But I can't fight anymore .

So before this interview , I have collected some on the Internet Android Develop relevant learning documents 、 The interview questions were reviewed and studied . I also reviewed the problems encountered in some projects I had done before , And found the corresponding solution . I thought there should be no such embarrassing encounter this time .

In order to facilitate the ability to review in the future , I hereby sort it out in Github On , If you need reference, you can go directly to me CodeChina Address ：https://codechina.csdn.net/u012165769/Android-T3 Access view .

The experience of just stepping into the path of architect

---

This time my plan for myself is to be an architect , But I know that architects are not for fun , There has to be a strong side , So what I write in my resume is just “ Architect direction ”. I am here K company It's the architect's direction , So I think it's necessary to work in this direction , Although it's not very good now , But after a year or two , Even if it's not very powerful , But it's also very close （ It's used here 《 Sun Tzu's art of war 》 A sentence of ：“ Please go up , Get it ; Ask for , Get it , Ask for the next , You will lose .” ）.

The idea comes from K My first job in the company was leader What I've been told ：『 For new things , If you feel that you have mastered , But it doesn't apply to the project , Is it meaningless , It will be forgotten after a long time .』 I'm glad I have a good boss （ I'm a double leader ,K company A The person in charge of the project is my leader, But my direct reporting target is K Deputy technical director of the company , Now I'm the boss ）, In his words, I often kick my ass to walk .

When I learned a lot of practical new technologies on the Internet , Give him a word at will , He can listen to me very attentively , And encourage me to bring these things into the project . Since then I've seen a lot of new technology , What feels right will be introduced into our project . From the later proof , It's very valuable .
