Answer
Annotations disappear after compilation. Frame the concept in practical terms so you can explain it during interview discussion.
Annotations with RetentionPolicy.SOURCE are only available in source code and are discarded by the compiler. They are useful for tools that analyze source code, like a code linter, but not for runtime behavior. For example, @Override is a common SOURCE retention annotation.
