I did it, I got through my first interview without any complete mind blanks!
One important approach that I think got me through was going in with the attitude of just being myself, being real, and speaking from the heart. What's the point in trying to be someone I'm not? If who I am is not what they want, then getting the job would be no good for either party. This line of thinking actually helped me relax and hence made the interview go all the better.
Secondly, I took along with me a folder of a few things that revealed a bit more of me as a teacher than the initial CV did. I put in a range of things from a variety of curriculum areas. Planning, worksheets, exemplars, etc. The true benefit of this was not so much giving it to the interviewees to browse through at their own leisure, but to actually hold it myself and talk from it as a springboard into sharing more about my approaches and philosophy of teaching. In this way I had my own prompts to ensure I covered key aspects that I felt were important. It also added strength to what I was talking about. As they say, 'a picture is worth a thousand words'. Additionally, I could pick it up again if any of their questions related to content that I had.
These two factors alone I would recommend to anyone going for an interview.
