What is the difference between @Repository and @Service annotations in the context of Spring?

The question about the duration of previous work experience usually implies specifying the period during which you worked there. For example, you can answer:

"I worked at Company X for 2 years, from June 2021 to May 2023. During this time, I participated in the development of several Flutter projects, which significantly improved my mobile development skills."

If you have no experience, you can honestly mention internships, educational projects, or current training.
