Java Full Stack Developer Interview Questions

1,048 java full stack developer interview questions shared by candidates

During the interview, we were asked to build a web application using React and Java Spring Boot. The application needed to take a string input, encrypt it, and then decrypt it when the encrypted message was passed back. After completing the task, there were a few follow-up technical questions related to React and Spring Boot. While I was comfortable with the React questions, I realized I wasn’t well-prepared for the Spring Boot ones. I believe that was the main reason for not being selected.
