As a Java background development engineer, you can prepare the following before the interview:
1. Project experience and technology stack: Review your past project experience, and prepare to introduce the projects you have participated in, the project scale, the modules you are responsible for, and the technology stack. For each project, prepare to be able to clearly articulate project goals, implementation plans, and results, and be able to explain your role and contribution in the project.
2. Core technologies and frameworks: Review and strengthen your own core technologies and common frameworks in Java background development, such as Spring, Spring Boot, MyBatis, etc. Make sure to have a deeper understanding of the principles and usage of these technologies and frameworks, and be able to give some examples of practical applications.
3. Database and SQL: As a background development engineer, database and SQL are very important parts. Review the basic knowledge of the database, commonly used SQL statements, and the principles of database design and optimization. Prepare to be able to explain concepts related to indexes, transactions, SQL optimization, etc., and to be able to apply them to solve real-world problems.
4. Performance optimization and tuning: understand common performance problems and tuning methods, including optimization of code, database and system. Review the performance problems and solutions you encountered in the project, and prepare to be able to talk about your optimization experience and ideas.
5. Network and protocol: For background development, an understanding of network communication and common protocols is necessary. Review the basic knowledge related to HTTP, TCP/IP, RESTful, etc., and understand commonly used network debugging tools and technologies, such as Wireshark, Postman, etc.
6. Interview questions and algorithms: Review common interview questions and algorithm questions, including data structures, algorithm ideas, and implementation of common algorithms. Understand commonly used data structures such as linked lists, stacks, queues, binary trees, etc., and be familiar with common algorithms such as sorting, searching, and dynamic programming. These questions can help you demonstrate your coding skills and problem-solving skills in interviews.
7. Interview preparation and mock interviews: Mock interviews are a very helpful way to prepare. Get a friend or colleague to act as the interviewer and conduct a mock interview with some common and technical questions. This can help you get familiar with the process and rhythm of the interview, and discover and improve your deficiencies in practice.
In addition, the communication skills and attitude in the interview are also very important. Prepare your own self-introduction and be able to clearly and concisely introduce your work experience and skills. Maintain a positive, confident attitude during the interview process, interact well with the interviewer, and demonstrate your teamwork and problem-solving skills.
Good luck with your interviews and your dream backend development job!
