What reasons make Spring a popular topic for discussion in development interviews?

Spring is popular in interviews for several reasons:

• Wide usage: Spring is one of the most popular frameworks for Java development, used in many companies.
• Modularity: Spring consists of many modules (Spring Core, Spring MVC, Spring Data, Spring Security, etc.), allowing knowledge testing in different areas.
• Inversion of Control and Dependency Injection: The main concepts of Spring — IoC and DI — are important for understanding application architecture.
• Automatic configuration: Spring Boot simplifies application creation, and knowledge of its principles is in demand.
• Testability: Spring makes writing tests easier, which is important for code quality.

In interviews, understanding these concepts, working with configuration, bean lifecycle, request handling, and security are often tested, making Spring an excellent topic for assessing skills.
