A common actual dialogue scenario is given below

Interviewer: Hello, please introduce yourself briefly.

Candidate: Hello, my name is Amos, I graduated from XX University and have three years of experience in software development. I am proficient in Java programming language, familiar with Spring, Hibernate framework, and middleware such as Redis and RabbitMQ.

Interviewer: Please describe in detail the project experience you have participated in.

Candidate: I have participated in the development of an e-commerce platform, mainly responsible for the development of user modules and order modules. I used the Spring framework for development in the project, and used Redis caching technology to optimize the reading speed of user data. I also use RabbitMQ as the message queue to ensure the reliability and consistency of the order.

Interviewer: Can you explain the concepts of data structures and algorithms?

Interviewer: Can you share the problems and solutions you encountered during the development process?

Candidate: In one project, we encountered the problem that the data reading speed was too slow. After analysis, we found that the performance was degraded because the database read operations were too frequent. We use Redis caching technology to cache user data in Redis to achieve fast data reading.

Interviewer: Please talk about your role and performance in teamwork.

Candidate: I am mainly responsible for the development of user module and order module in the team. I work closely with product managers and testers to ensure the quality and user experience of the product. I also helped other colleagues solve some technical problems and maintained good communication and cooperation with the team.

Interviewer: What are your future career plans and development goals?

Candidate: I hope to be an excellent software development engineer and a team leader in the future. I will continue to learn and improve my skills to make greater contributions to the company's development.

Interviewer: Do you have any questions for us?

Candidate: What are the company's requirements for the skills and qualities of software development engineers?

Interviewer: We hope that software development engineers can be proficient in at least one programming language, master basic computer knowledge, understand software development process and agile development methods, have good programming habits and coding style, as well as good communication skills and teamwork spirit.

Candidate: Thank you. I am very interested in the company's requirements and work content. I look forward to joining your company and developing together.

Interviewer: Thank you for your time and attention, we will contact you as soon as possible.

You should have noticed that in the above dialogue, I only listed the most common dialogue frameworks. In fact, when we are preparing for the interview, we can prepare a fuller and more vivid story in advance for each possible question type, and tell your application and understanding of technology in combination with actual work scenarios.
For example, expand the answer to the following:

Interviewer: Hello, please introduce yourself briefly.

Candidate: Hello, my name is Zhang San. I graduated from a certain university and have three years of experience in software development. I am proficient in Java programming language, familiar with Spring, Hibernate framework, and middleware such as Redis and RabbitMQ.

Interviewer: Please describe in detail the project experience you have participated in.

Candidate: I used to participate in the development of an e-commerce platform, responsible for the design and development of user modules and order modules. In the user module, we use the Spring framework for development to realize functions such as query, modification and deletion of user information. However, due to the huge amount of user data, the speed of directly reading data from the database is very slow, resulting in a decline in user experience. In order to optimize this problem, I introduced Redis caching technology to cache user data in Redis, thus realizing fast data reading. In the order module, we use RabbitMQ as the message queue to ensure the reliability and consistency of the order. When an order is generated, we send the order information to RabbitMQ, and then use multiple consumers to process the order, thereby improving the concurrency and reliability of the system. This project gave me a deep understanding of the practical application and importance of technology. By using the Spring framework and Redis caching technology, I learned how to optimize the system and improve the throughput and performance of the system. By using RabbitMQ, I learned how to achieve reliable message delivery and ensure the data consistency of the system. In short, this project has given me a deeper understanding of the practice and principles of software development, and it has also made me more confident and confident in facing future challenges.

Interviewer: Can you explain the concepts of data structures and algorithms?

Candidate: Data structure refers to the way computers store and organize data, such as arrays, linked lists, stacks, queues, etc. Algorithm refers to a series of steps to solve a problem, including sorting, searching, graph processing, etc. Data structures and algorithms are a very important part of software development, and I have experienced their role deeply in my work experience. In an e-commerce platform I participated in the development of, due to the huge amount of user data, we used a hash table to speed up user queries, which greatly improved the query speed. At the same time, we also use the quick sort algorithm to sort the order data, thus improving the efficiency of order processing. These experiences made me deeply realize that data structures and algorithms are an integral part of software development, and they can help us do our work more efficiently.

Interviewer: Can you share the problems and solutions you encountered during the development process?

Interviewer: Please talk about your role and performance in teamwork.

Candidate: In a previous company, I was involved in the development of a large e-commerce platform. I am responsible for the development of user module and order module. At the beginning of the project, the product manager and UI designer in our team and I discussed the requirements of the user module. From their point of view, I considered user experience and interface design, and finally designed a clean and effective user module, which was integrated with other modules.

During the development process, I encountered a problem: due to the huge amount of user data, the speed of directly reading data from the database is very slow, resulting in a decline in user experience. Through the research on Redis caching technology, I decided to cache user data in Redis, thus realizing fast data reading. This solution not only improves the user experience, but also saves the company a lot of money.

In the development of the order module, I work together with another development engineer. We discussed the requirements of the order module, and designed the order process and rules together. We use RabbitMQ as the message queue to ensure the reliability and consistency of the order. When the order is generated, we send the order information to the message queue, and the consumer generates the order through the message in the queue, thus ensuring the reliability and consistency of the order.

In the team, I actively cooperate with other developers and testers to solve the problems encountered. In my opinion, technology is a process of teamwork, and only by supporting and cooperating with each other can better results be achieved. Therefore, I have always maintained a good communication and collaboration spirit with my team members.

This project gave me a better understanding of the importance of teamwork and how to achieve rapid business iteration and innovation through technology and teamwork. I believe that in the future work, I will be able to bring more value to the company and realize my career goals.

Interviewer: What are your future career plans and development goals?

Interviewer: Do you have any questions for us?

Candidate: What are the company's requirements for the skills and qualities of software development engineers?

Candidate: Thank you. I am very interested in the company's requirements and work content. I look forward to joining your company and developing together.

Interviewer: Thank you for your time and attention, we will contact you as soon as possible.
