The basic requirements of a programmer included the following: ** 1. In terms of technical knowledge ** 1. ** Basic programming languages ** - A deep familiarity with programming languages, such as the collection class, parallel packet, IOO/NIOs, jvmp, memory model, generics, exceptions, reflection, etc. It is best to read the source code to understand the underlying design. During the interview, knowledge points such as ConcurrentHashMap, CopyOnWrite, thread pool, NAC, AQL, virtual machine optimization, etc. may be involved. - Mastering data structures and algorithms was helpful in organizing and processing data. It was also an important way to solve problems. - Familiarity with code writing specifications, including but not limited to naming specifications, code format, etc., will help improve the code's legibility and survivability. - Understand the basic process of software development, such as the software development life cycle, to ensure that the development process is standardized and systematic. - Master version control systems such as Git for efficient code management and collaboration. 2. ** Knowledge of the database ** - In-depth understanding of MysQL, Redis, Mongodd and other database. Take MysQL as an example. You need to know the common parameters, the choice of storage engine, the common index engine, how to design tables, how to optimize sql, and how to adjust the class according to the execution plan. You also need to master the design and optimization of the sub-database and sub-table. Redis is an essential skill. 3. ** Server and framework related knowledge ** - Learn about servers such as nginx and tomcat, which are often used in Internet projects. - Master RPC related knowledge, including network protocol, serialization technology, and so on. You must also have a deep understanding of popular RPC framework (such as domestic Dubbo, open source Spring Cloud related technology stack). - For JMs (such as ActiveQL and Kafka, which are commonly used in domestic enterprises), you need to understand the principle. ** 2. Ability ** 1. ** logical thinking ability ** - A program was a manifestation of logic, and a programmer needed to have clear logical thinking. Able to break down complex problems into simple steps, solve problems in an orderly manner, and design efficient and easy-to-maintain algorithms. You can train your logic skills by doing more algorithm questions, participating in coding challenges, reading and reviewing other people's code. 2. ** programming ability, algorithm ability, and architecture ability ** - The ability to program was reflected in the ability to write high-quality code. Arithmetic ability required one to master basic algorithms. 30K programmers had certain requirements for algorithms and attached great importance to them. The architectural ability involved the design and planning of the entire software system architecture. 3. ** Continuous learning ability ** - The technology field was developing rapidly, and new programming languages, framework, and tools were emerging. A programmer needed to have the ability to learn continuously. Not only did they have to master new knowledge, but they also had to be able to quickly apply this knowledge to solve practical problems. It could be improved by making study plans, attending technical conferences, reading technical blog posts and forums, etc. 4. ** Problem solving ability ** - There were all kinds of problems in the programming process. The programmer had to be able to quickly locate and solve the problem, foresee potential problems, and propose preventive or optimization measures. This required a deep understanding of the code, as well as the necessary skills to do so. 5. ** Teamwork Ability ** - Most software development was a team collaboration project, and programmers needed to have good communication skills, be able to accurately and clearly express their ideas, and communicate effectively with team members. Teamwork can be improved through code reviews, team meetings, and pairing programming. You also need to understand agile development methods (such as Scrum and Kanban) to adapt to the team's work rhythm and collaboration model.
