I. Introduction
It is now the end of the month in October, and the craze for job hunting and interviews has gradually faded.
When the tide goes up and down, some people get their favorite offer from it; some people take a trip and get nothing, or get little, and are not satisfied; others are watching and waiting for the next opportunity.
Here is an analysis of the current interview market, to take you to understand where you are, and to share useful information to help you improve your combat effectiveness.
Face Sutra
I was interviewing for Tencent's Android development position. The interviewer asked a lot of Java knowledge, and didn't even ask an Android-related question (I don’t know if this is normal...). I am very distressed. The following is a note Some interview related questions.
1. Introduce yourself (this is nothing to say, introduce who is the last name and first name, where you graduated, and what related projects you have done)
2. Several states of java multithreading. The answer was not good, only the ready, running, and blocking state was answered.
3. Data structure, red-black tree. I majored in electrical before, and I didn’t learn data structure, so I just said I can’t pass.
4. I don't understand the Java virtual machine. I don't know much, I only know the GC recovery mechanism.
5. I don't understand Java design patterns. I don't understand, I have only heard of singleton, observer mode.
6. Look at the Mqtt protocol written in my project, and ask me if I understand the Amqp protocol. I don't understand, I talked about some Mqtt topic subscriptions and related issues.
7. Asked how threads are loaded in the JVM virtual machine. Oh, I don’t know.
8. Asked how static static is loaded. The answer to this feeling is okay, it is a series of processes of class loading.
9. I asked if there is a unified exception handling mechanism in the project. No, it's all trt/catch.
10. I asked whether the related knowledge of inheritance was used in the project. No.
11. Ask how you usually study. Go to CSDN, GitHub, find relevant information, and search for the corresponding solution if you encounter any problems.
I don’t know why I’m applying for Android, it’s all about Java-related knowledge, maybe Java is really important for Android development...heart tired...
to sum up
Finally, in order to help everyone deeply understand the principles of Android-related knowledge points and interview-related knowledge, here are the 14 sets of real interview questions that I have collected and compiled by Tencent, ByteDance, Ali, Baidu and other 2020 interview questions . I have organized the technical points into Video and PDF (actually took a lot more effort than expected), including knowledge + many details.
There are a lot of materials for learning Android on the Internet, but if the knowledge learned is not structured, and when you encounter problems, you just taste it and do not research in depth, then it is difficult to achieve real technological improvement. I hope that this systematic technical system will provide you with a direction reference.
Home has a direction reference.
