Having spent several years of my life as an interviews, I like the sample answers you set out in this and particularly the guidance to do everything possible to find out what matters to the interviewer before answering. Ultimately interviews are influencing conversations. If you'd like to check out more on the subject of building your influence (relevant for interviews and for lots of other workplace conversations) I'd recommend Robert Cialdini's work (www.influenceatwork.com). He has some really valuable points too (such as the value of the word 'because'. E.g. I'd feel I am an ideal candidate because....). Cialdini's research shows that simply using this word will increase your influence. And he recommends keeping answers simple and short if you want to influence better too. For example, one relevant example will be more powerful than four or five relevant examples - the latter will actually turn people off!
