Today I will share with you the T1-T9 level of the position developed by Tencent internally, with the professional knowledge, ability and technical points. As for the depth of knowledge points, it depends on the degree of understanding of the technical points and knowledge points. Personally, the knowledge points are understood. The degree of this has a lot to do with the level of your positioning.
Many friends told me that in the process of learning programming, I don't know what level I am at, and I don't know how far I can get a job, what kind of job I can find, and what kind of pay I can get. I believe this is a worry for many people.
These points are here to explain to you, the category of ability, the description of ability, and the corresponding job classification.
The capability category is divided into: code capability, operation capability, security capability, architecture capability, engineering literacy
1. Description of code capabilities: the ability to create high-quality compliant code (with low coupling, high scalability, high performance, security, etc.) and related tools.
2. Operational capability description: The ability to flexibly apply operational data, big data analysis and other means to analyze system operation status from the dimensions of cost, quality, and efficiency, optimize services, and achieve the goals of good user experience, high operational efficiency, and rational use of resources.
3. Security capability description: master the risk of security vulnerabilities in the process of system design and implementation, improve the availability and security of the system, and protect business and data from infringement.
4. Architecture capability description: the ability to flexibly apply the underlying infrastructure, design and build high-quality distributed services (with high availability, strong scalability, high data reliability and security, and strong operational controllability).
5. Description of engineering literacy: the ability to grasp the main contradictions, core challenges and key technical difficulties in engineering projects, organize and coordinate resources, and achieve goals.
Self-study takes a long time, the technology stack is not perfect, the structure is not structured, and the self-discipline is poor. To share with you a learning video click: C/C++Linux server development / background architect [Zero Sound Academy]-learning video tutorial-Tencent Class
Don’t say much, just take a picture
In this picture, the knowledge that needs to be learned is divided into 9 aspects: language foundation, data structure and algorithm, database, network principle, operating system, network programming, distributed architecture, cloud native and some soft skills.
