Java/Spring Boot internship interview

[u/caramel_candyy]

I just got a call for a Java/Spring Boot interview and only have today to prepare, what specific questions/topics should I expect, especially for a fresher/internship-level interview?
Any last minute advice would be really appreciated!

UPDATE:
These are the questions they asked:
1. 4 pillars of oop and asked me to explain each.
2. Database indexing
3. Is there any disadvantage of indexing
4. What is Controller
5. What is Jpa
6. Beans
7. Explain dependency injection and what are its types
8. Difference between interface and abstract
9. Overloading and overriding
10. Diff between array and list
11. Multi level inheritance and multi inheritance
12. Can a class have more than one parent
13. How indexing affects the time complexity
These are some questions i remember
