Hope everyone is having a good weekend

I just had two questions re interviews:
1. When it comes to 'Why this firm?', should you still link your points to yourself? E.g. if you mention a specific practice area, their secondment opportunities etc., should you mention a personal experience/attribute that supports why you're even mentioning these points?
2. For scenario-based questions (e.g. 'What would you do if [...]?') is there a template that can be used (like the STAR structure for competency questions)? I'm asking because, at the start of your responses, couldn't you just say that you could refer to the firm's policy manual/contact your supervisor if there is an issue?
