When it comes to Internet giants, many people have included ByteDance, but you must know that other bigwigs have had their current status after more than 20 years, and ByteDance has only been established for 7 years.
Today, ByteDance is often compared to Tencent because their head-to-head competition is almost doomed. Tencent starts from connecting "people", then connects "content", and connects everything; while ByteDance starts from "content", touches users' emotions, and then connects "people".
At present, ByteDance has entered Tencent's strategic hinterland, launching round after round of offensives. From flying chat online to challenge the WeChat\QQ social empire, today's headlines against Tencent News, both sides are good at winning games, losing to Tencent's game dominance as game recruits, to Douyin-based short videos throwing off Tencent's several positions, diversifying layout to surround Tencent The full-license financial empire, ByteDance is coming.
The industry's voice for ByteDance is very high, and some people predict that its future is likely to be the third largest Internet company in China after Tencent and Alibaba, and its future is limitless.
Zhang Yiming believes that in order to develop an Internet company, the main thing is to be able to employ people. He said, " It is very easy to screen candidates with time and product magnitude. But the most important thing in recruiting is to find the most suitable people. The real fit is to focus on the fundamentals of people. School, relevant experience, and title are not that important .”
In other words, it is still a question of ability. At present, the salary of byte programmers is basically the same as that of big factories such as BAT, and the threshold is relatively low. As long as you have enough ability, you can basically enter.
Therefore, it is necessary to have an in-depth understanding of the interview knowledge points in advance, and I have specially compiled a rare "JAVA Advanced Collection". This PDF face-to-face knowledge points includes five major parts and 26 knowledge points.

1. Java knowledge part
Now the interview pays special attention to many basic principles, but many people do not have a thorough understanding of some core principles, especially some core basic knowledge points of Java, such as JVM, commonly used algorithms and data structures, etc. As the so-called high-rise building starts from the ground, only by grasping the basics firmly can you go further, and you can quickly master the constantly updated technology, and at the same time, you can stand out in interviews and work! The following is the Java knowledge that must be mastered. Parts, there are a lot of content, all are some key knowledge!!!
1. Java basics:
2. Java Collections:
3. Multi-threaded concurrency:
4.java virtual machine (JVM):
JVM is the only way for junior Java programmers to grow up. Before learning JVM, you only need to know that the code is compiled into Class, and the virtual machine loads the Class to run. After learning JVM, you can deeply understand the process of code compilation to loading. , the creation and garbage collection of objects in memory, and the rapid positioning of performance problems in daily development. Of course, it is also an indispensable bonus item for the interview.
5. Data Structures and Algorithms
Which data structures (lines, chains, heaps, stacks, queues) and where are they useful in Java. 8 big algorithms (time complexity, space complexity, memory, CPU impact) and where they are applied. KMP search algorithm, binary search, recursive algorithm (writing method, memory impact). Numbers, graphs and places where they are used. hash table, and where it is used in practice.
Second, the database part
Recommended reading: "High Performance MySQL" "MySQL Technology Insider: InnoDB Storage Engine (2nd Edition)"
3. Open source framework part
As a lightweight Java development framework, Spring applies interface-oriented programming ideas throughout the entire Java system, so it is often mentioned in Java interviews.
4. Distributed high concurrency architecture part
This part is about distributed architecture knowledge, including Redis, Zookeeper, database performance optimization, load balancing, and more!
5. Knowledge of Microservices
There are many small partners who have been interviewed recently. I hope to help more people pass the interview with Dachang successfully. If you need to click on the business card below to scan the code, you can get it for free, no routines! ! !
