The new year is about to pass, and everyone may have new plans. It is now the golden nine and silver ten. Many friends have more or less want to change their current working environment, so they are willing to change jobs. Ideas sprouted naturally!
Someone recently left a message hoping that my senior can sort out some interview questions and apply them to the subsequent interviews. Today I will mainly sort out the common questions asked by Android programmers in interviews. I hope it will be useful to you if you need them.
Interview learning routes & ideas
You can first prepare for the technical interview from the following aspects. The following examples are very detailed! ! !
- Generics principle, reflection principle, Java virtual machine principle, thread pool principle
- Annotation principles, annotation principles, serialization
- Activity knowledge system (Activity life cycle, Activity task stack, Activity startup mode, View source code, Fragment kernel related, service principles, etc.)
- Android Framework knowledge system (Bidner, Handler, AMS, WMS, PKMS source code)
- Code framework structure optimization (data structure, sorting algorithm, design pattern)
- APP performance optimization (user experience optimization, adaptation, code tuning)
- Hot repair, hot upgrade, Hook technology, IOC architecture design
- NDK (c programming, C++, JNI, LINUX)
- How to improve development efficiency?
- MVC丶MVP丶MVVM、MVI
- jetpack component library
- WeChat applet
- Hybrid
- Flutter
- Kotlin
With the review ideas in mind, it is also necessary to combine it with past practical experience. There are many online interviews, but there are few standardized and concise analysis of interview questions . Here I will share with you the interview questions of various major companies in 2023. The analysis collection includes analysis of 1,600+ real interview questions from Alibaba, Tencent, Huawei, JD.com, Meituan, ByteDance, Baidu and other super first-tier companies, helping everyone to have a deeper understanding of the interview ideas of large companies and to be more fully prepared for the challenge. Interview with a big factory, get it directly at the end of the article .
