This year, Jianzhi Tencent

I believe everyone has started , Today, I specially asked a friend of Tencent for some interview related information and question brushing notes , The content covers the basics of computer 、Java、JVM、spring、 Design patterns 、 Algorithm 、 Microservices 、 Distributed 、 Dachang Mianjing, etc ... Very high quality ！！！ Don't look at the interview questions .

Whether you want to go for an interview or not recently , I recommend you save it first , I'm sure I can use it later ！ The following is part of the information display ：

Java Core knowledge points ：

Java Architect's sunflower Scripture , this 30 A knowledge point needs to be mastered .

JVM：

JVM Can be run Java Hypothetical computer of code , Includes a set of bytecode instructions 、 A set of registers 、 A stack 、 A garbage collection , Pile up and A storage method domain .JVM Is running on the operating system , It has no direct interaction with the hardware .

Spring principle

It is a comprehensive 、 Enterprise application development one-stop solution , Through the presentation layer 、 The business layer 、 Persistence layer . however Spring Can still integrate seamlessly with other frameworks .
 

Netty And RPC

Netty It's a high performance 、 Asynchronous event driven NIO frame , be based on JAVA NIO Provided API Realization . It provides the right TCP、UDP And file transfer support , As an asynchronous NIO frame ,Netty All of the IO Operations are asynchronous and non blocking , adopt Future-Listener Mechanism , Users can easily obtain the information by active or notification mechanism IO Operating results .

Multithreading and high concurrency ：

Internet age , How to meet the challenge of high concurrent traffic . And as a technology developer , How to deal with the skill crisis brought by technological change . Based on the technical changes brought about by the evolution of traditional architecture .

In the depth and breadth of technology has been improved by leaps . What the Internet industry needs T Type talent
 

Microservices

Service registration is to maintain a register , It manages all the service addresses in the system . When the new service starts , It will give its address information to the register . The relying party of the service directly asks the register for Service Provider Just the address . At present, there are many tools for service registration ZooKeeper,Consul,Etcd, also Netflix Family eureka etc. . There are two forms of service registration ： Client registration and third-party registration .

database

Database storage engine is the bottom software organization of database , Database management system （DBMS） Create with data engine 、 Inquire about 、 Update and delete data . Different storage engines provide different storage mechanisms 、 Indexing techniques 、 Lock level and other functions , Using different storage engines , just so so Get specific features . Now many different database management systems support many different data engines . Storage engines mainly include ：1. MyIsam , 2. InnoDB, 3. Memory, 4. Archive, 5. Federated .

Message middleware

Kafka It's a high throughput 、 Distributed 、 Based on the release / Subscribed message system , By the first LinkedIn Companies to develop , Use Scala Language writing , At present, it is Apache Open source projects for .

RabbitMQ It's a by Erlang Language development AMQP Open source implementation .

Data structure and encryption algorithm

The position of data structure and algorithm is self-evident for a programmer .

Master data structure and algorithm , No matter for reading the framework source code , Or to understand the design idea behind it , Are practical .

PS： Dry cargo is full. Without any moisture ！ There's a lot more , It's different A show of . If you need it, you can get it by yourself . I hope it can help you more smoothly on the way of study and interview ！2022 Enter the large factory   Get a high salary ！
