Hello Everyone. Thank you for reading this post. I have an onsite interview with Amazon. I have 3 Coding round and 1 OOD round. I have some queries regarding OOD round.

Does interview ask to draw UML Diagrams?
What questions can be ask (as a scope or constraint) for OOD questions. (For Example, I have asked to design Amazon Shopping Website. So what kind of questions I can ask as a constraint? )
Do we have to write whole code starting from MAIN?
What are the interviewer's expectations regarding OOD Round?
General guidence regarding OOD round?
