Foreword
This paper would like to share with you is how to prepare for the interview and the interview Ali process proceeds think, I hope you can help.
First of all, may let you down, this article does not have an answer interview questions at great length. If you want to see content in this area, you can see my previous article. Thanks for attention
A Dian Responsibilities
First we look at the job responsibilities
1, responsible for the Android mobile platform development work
2.Android framework for the development and maintenance, SDK development
- Technology architecture upgrade optimization, improve the efficiency of business R & D
Two Dian Requirements
1, more than three years, Android client development experience
2 Dian JAVA solid foundation of understanding the basic framework io, multithreading, collections, etc., have a certain understanding of the JVM principle
3, master Android common components, the principles of the framework, and technology
4, proficient Android underlying framework, proficient in Android performance tuning, familiar with the Android source code
5, have a strong sense of responsibility and team spirit, good communication and cooperation; to complete the design and independent coding
Wed and on how to write a resume highlight
I think the role of the resume is to make people look at your resume quickly Dian accurately capture useful information, see your unique
1.who are you? (Who are you?)
2.What DID you do? (What did you do?)
3.What do you Stand OUT from (what is special about you?)
Highlight important these days, in fact, it is enough
3.1 Content
Mainly it contains several of the following modules:
basic information: name, phone, email, personal website (GitHub)
Work experience: company name, working time, job content (outlined in charge, what is involved in the business)
Project Experience: The most important thing none of them! Expand Description
expertise: plus or minus itemized breakdown is possible, carefully, expand the description
Education: school name, school time
Others: Quick description anything you want the interviewer to know, such as community influence: how much GitHub Star, Nuggets levels, etc.
Project experience is one of the most important for the development is part
3.2 Highlights
Work: What is the business background of this project, are there any more Niubi place in business, how to promote a business to run, and so
on technology: the overall technical realization of this project is the idea of how the project compares with what fast hardware technology to solve difficult problems, and so what
What do ten million write proficient, unless you're really fast hardware, or a project has a very fast hardware technology, but not what you write, but you are not very understanding.
Good-looking skins stereotyped, funny soul better than one
in the ordinary course of business:
- The project did things fast hardware
- What did you do things fast hardware in the project
- With what fast hardware technology to solve the difficult problem of what
Project experience is a very important part, it will be fine to ask, his own prominent place Niubi understand and speak
3.3 on their skills
Of course, I want to get 30-50K expertise have opposed
JAVA solid foundation of understanding the basic framework io, multithreading, collections, etc., have a certain understanding of the principles of JVM
master Android common components, the principles of the framework, and technical
proficiency Android underlying framework , performance tuning proficient Android, Android source familiar with
keen Android development projects, proficient SDK, hot fixes, performance optimization, etc.
Professional skills might be a plus items can be reduced breakdown, tricky

简历上写的项目，仔细认真的过一遍。还有就是关于业务的一些深层次的东西，得好好思考一下。
一些开放性问题还是需要好好思考一下，顺便也准备一下 HR 面可能会问到的一些问题。
在复习某个部分时可能会引出其它知识点，如果也不是很清楚的话也需要系统的再复习一下。
Knowledge broad and rapid development, we should focus on basic foundation is the most important

Precautions:
- Everything there is no standard, no questions have to be resourceful, mostly have their own thoughts and insights
- Ali fact, relative to other companies, and so on academic requirements of a relatively developed
- There is a forum on technical drink HR surface. Technically about 3-4 rounds, there may be written
- Technically might Telephone + video interview, or about the interview time. By successfully before last few faces there is a final surface
- Currently there are just friends Tencent, Ali, the US group. There are previously Huawei, millet, iQIYI friends and so on, need to interview you can find me some advice to help you follow up
