Regarding the first question: It's my understanding that you can normalize a RDBMS. In the strictess sence you have to reference other data in an RDBMS, but I think if you say that you cannot normalize a RDBMS in an interview it would imply that normalization is not an optimization process. Analytics Vidhya has an article "How to Normalize Relational Databases With SQL Code?"
