Actually, that's a question I've heard being asked - how does your work as an English teacher fulfil the principles of CfE. The important thing to remember is that CfE isn't about all the outcomes but about teaching methodology - how do you provide choice/motivate pupils/give them chances to take responsibility for their own learning. I've heard questions about how you will help children achieve the four capacities too. It's possible you might get asked about cross curricular work too and watch out for questions about your new responsibilities as a teach of numeracy and H&W too. Find one positive thing about it that you really believe and focus on that.
