"Paid paddling" stealthily brushes Brother Ali's face scriptures, challenges bytes three times, and finally achieves positive results

Hello, I am very pleased to inform you that after passing the interview evaluation and discussion, we sincerely invite you to join ByteDance...

A few days ago, a friend went to a major Internet company for an interview (Alibaba, JD.com, Meituan, Tencent). After the interview, he would send me some interview questions.A friend desperately squeezed into ByteDance and got an offer. I believe that many people will be curious about the interview questions and answers. I will share them with you below.I deliberately sorted it out. There are many questions that cannot be explained clearly in a few sentences, so I simply asked a friend to record some videos to address these interview questions.The answers to many questions are actually very simple, but the thinking and logic behind them are not simple.

Whether you are a novice or a veteran who has been working for three or five years, whether you are a major manufacturer of gold, silver and silver, or you want to prepare for the gold, silver and silver in 2023, you should take a good look at this information.It is very comprehensive and covers almost all technical cuttings~ Without further ado, this information is divided into 3 parts, including (technical PDF + interview questions + interview technical guidance): Java Architect Growth Notes: including Basic knowledge, Java collections, JVM, multi-threaded concurrency, spring principles, microservices, Netty and RPC, Kafka, journals, design patterns, Java algorithms, databases, Zookeeper, distributed caches, data structures, etc.Rich, has helped many people win offers from first-tier Internet companies.There are a total of 31 knowledge points.

Because there are too many details in the PDF document, only the chapters with some knowledge points have been edited for a rough introduction, and there are more detailed contents in the small nodes of each chapter!The following is a list of some chapters, JAVA basics must first be a review of Java basics, which can be used in both study and work. Learning Java basics well is like laying a foundation like building a house.Shake the mountain.

Spring Principle It is a comprehensive, one-stop solution for enterprise application development, which runs through the presentation layer, business layer and persistence layer.But Spring still integrates seamlessly with other frameworks.

DatabaseThe database storage engine is the underlying software organization of the database. The database management system (DBMS) uses the data engine to create, query, update and delete data.Different storage engines provide different storage mechanisms, indexing techniques, locking levels, and other functions. Using different storage engines, you can also obtain specific functions.Many different database management systems now support a variety of different data engines.The main storage engines are: 1.Mylsam, 2.InnoDB, 3.Memory, 4.Archive, 5.Federated.

KafkaKafka is a high-throughput, distributed, publish/subscribe-based messaging system, originally developed by Linkedln, written in Scala, and currently an open source project of Apache.

Data structure and encryption algorithm

StormStorm is a free and open source distributed real-time computing system.With Storm, it is easy to reliably process unlimited data streams. Like Hadoop for batch processing of big data, Storm can process data in real time.

Load Balancing Load balancing is built on the existing network structure, it provides a cheap, effective and transparent method to expand the bandwidth of network devices and servers, increase throughput, and strengthen network data processing capabilities, Improve the flexibility and availability of the network.
