Look at the huge number of positives against the samll number of possible queries. Where does the balance lie? I make it 10 absoloute postives (from the people who would be wroking with you and managing you) against 3 possible queries (from the HR bod who is probably up her own arse (apologies to any HR people).
Query 1, you think is bollocks (so do I) so that one doesn't count.
Query 2, we talked a bit about that when we met re: having some models on which to base your answer (e.g. analyse, plan, do, review), and giving specific examples of those skills even if it is another context.
Query 3, what YOU seem to do is what I would call 'situational leadership' i.e. the approach you would take is dependent on the situation. It is the most flexible and emotionaly intelligent leadership / management style, so excellent, good on you (not many people are good at it or understand it - they have only 1 or 2 preferred styles). Just go back to giving examples. So if they ask what would you do in x situation, then you could say that you have 2 examples: one where you were clearly responsible, took the lead, made the decisions etc, and another where you made a significant contribution but someone else had the lead because of their specific techincal knowledge or their broader understanding of a complicated situation. Then tell them that you think that your examples demonstrate an adaptive style of leadership.
It is good to focus on what they said before, but you know they are unlikely to come back and ask you the same things, and if they do, just focus on the 10 great things they said about you.
It is not surprising that you are feeling a little nervous (you need all those neurotransmitters to help you perform at your peak), but do not confuse those nervous feelings with a lack of confidence in who you are. You rock woman. Go for it.
