Today is the first day of September, and it is also the beginning of the Golden Nine and Silver Ten. As a fresh graduate or a job seeker who is looking for a job, it is very important to make some preparations.
First, you need to conduct a comprehensive self-assessment of yourself, understand your skills, strengths and interests, and clarify the position or industry direction you want to work in
Secondly, build a complete resume that highlights your learning experience, project experience and skills
At the same time, prepare the knowledge and skills required for interviews and conduct mock interviews to improve your confidence and coping ability
In addition, when facing technical positions, the most important thing is your own technical foundation.
technical foundation
A solid technical foundation is the prerequisite for interviewing with major manufacturers
- 1. Computer basics: TCP/IP, HTTP/HTTPS, Socket, (Linux) operating system, database related.
- 2. Java basics: object-oriented, reflection, generics, and collection class libraries.
- 3. Java concurrency: thread/thread pool, volatile, pessimistic lock/optimistic lock, etc.
- 4. Jvm virtual machine: such as execution process, JMM model, Java's GC recycling principle, and class loader.
- 5. Data structure and algorithm: The sword refers to the Offer + LeetCode high-frequency question set.
- 6. Android basics: startup mode, animation, custom View.
- 7. Android advanced: performance optimization, Binder, AIDL, inter-process communication, AMS/WMS/PMS, event distribution, sliding conflicts, View drawing process, important Android source code and open source library analysis.
- 8. Android high-tech: modularization, componentization, hot update, and plug-in implementation principles.
The above basic knowledge is regarded as the basic requirements, and most of them require daily accumulation. It is best to answer the basic questions about the specific application scenarios and the problems solved.
After all, interviews are like exams, just like what we do before the college entrance examination sprint, it is nothing more than understanding and memorizing every knowledge point. Of course, passing the interview requires certain skills, but it definitely does not rely on forgery and cheating. After a period of time to calm down and practice in seclusion, when spring comes, you can go out to harvest, enter a big factory, and double your salary. Wouldn't it be wonderful?
In order to facilitate everyone to better classify and study, here is a thousand-page set of Android interview question bank + analysis notes for job hopping and salary increase, covering 21 core technologies, technical key points of major manufacturers, interview difficulties, and advanced points to help everyone "sharpen their skills in battle" , get it at the end of the article if you need it.

Conclusion
For interviews with large companies, the last thing I want to emphasize is that mentality is really important and is the key to determining your performance during the interview process. If you cannot perform normally, you may miss the offer because of a small mistake, so you must pay attention to it. stand up. Another reminder, sufficient review is the key to eliminating your nervous state of mind. But if you review enough, you will naturally be much more confident during the interview process.
