The interview went well overall.

The interviewer started by asking basic Java-related questions, covering fundamental concepts such as data types, collections, and exception handling. They also tested my understanding of OOPs (Object-Oriented Programming) concepts, including encapsulation, inheritance, polymorphism, and abstraction, along with real-world examples to demonstrate how these principles are applied in practice.

Next, there were a few questions about the Spring framework. They focused on Spring Boot annotations, dependency injection, and the difference between @Component, @Service, and @Repository. They also inquired about Spring Data JPA and how to handle transactions effectively.

Additionally, the interviewer presented two output-based questions. I had to analyze small code snippets and predict the output. These questions tested my understanding of Java syntax, control flow, and tricky edge cases.

Finally, there was one algorithm-based coding question, which required me to write an efficient solution. It tested my problem-solving skills and knowledge of data structures and algorithms. The problem involved array manipulation and optimal search techniques, where I had to focus on both correctness and performance optimization.

Overall, the interview was a good mix of theoretical and practical questions, covering core Java, the Spring framework, and problem-solving abilities.
