First Round Phone Interviews w/ Clean Energy IB

Hey everyone, I've got a back-to-back set of first round phone interviews today with two analysts at a small clean energy shop. What sort of questions should I expect from the analysts? (i.e - should I expect more technical or more fit questions from them?) Also, I was fortunate to be selected for this but don't have any long-standing passion for the industry to be honest. Is there a good answer to the question 'why us' that doesn't involve lying about having some life-long passion for clean energy?

Thanks a lot for your help guys.
