It's worth seeing. Interview sites and interview skills

origin

With Android The development industry is gradually saturated , Yes Android The interview requirements of developers are becoming higher and higher , Whether to master the underlying source code , It's the interviewer who measures a Android An important basis for developers . Whether you have read the source code can also judge your learning ability and way of thinking to a great extent . No matter how many years of development experience you have , The interview was asked to answer the source code question , 

《Android Summary of learning notes + Latest mobile architecture video + Big Android interview questions + Project actual combat source code handout 》 Free open source Hui Xin search official account 【 Advanced programming 】

  Not only will it lose its value 、 Not to mention cutting salaries , I can't even pass the interview ！

All kinds of online source code analysis articles and blogs are diverse 、 Uneven, some good and some bad . clutter 、 Or the content quality is too shallow , scattered 、 fragmentation , I can't connect when I always look at it .

therefore , Bloggers use their leisure time , It took nearly three months to Android Most commonly used in development 、 The most frequently asked interviewers 18 Class source code is integrated into a set of system knowledge notes PDF, total 487 page ,18 Chapters ！ I believe that after reading this document , You will be right Android The development of various types of core source code has a more in-depth 、 A more systematic understanding of .

Because there is so much , Avoid affecting your reading experience , Here's just a screenshot of the table of contents ,487 Detailed and complete version of 《Android  Development of relevant source code analysis 》 How to get e-book documents ：** give the thumbs-up + Focus on , Then private message keywords  【666】** You can add my personal wechat and send it to you （ Free of charge ）. You are also welcome to discuss with me Android Technical problems

Catalog :

Because there are many questions , Space limitation , The interview questions in the article are not all shared with detailed analysis , But it's a detailed PDF Documents can be shared with you , At the end of the article, we get the free way

Looking at the interview questions can be for an interview , It can also be a kind of leakage of what you have learned , Learn more about some core knowledge points

Okay , Today's sharing is here , If you have any questions about the interview , Or just graduated and work for a few years confused, do not know how to prepare for the interview and break through the status quo to improve themselves , I don't know enough about my future. I don't know how to plan for it , Let's see how peers break through the status quo , How to learn , To absorb their interview and work experience, improve their future interview plan and career planning .

Here is a collection of interviews I have participated in since my work
