Hi Chris. I included as much as I could in the three pages we were expected to hand in! I started by summarising the objectives of my research and the methodology I intend to use. I highlighted some key publications that I read, what I have written so far, the archival material I found; the papers that I presented at conferences; libraries/ archives/ institutions where I worked; awards, courses attended, etc. what I intend to do in the forthcoming months.
The interview was fairly straightforward, but I had a couple of unexpected questions. Nothing to worry about anyway. Good Luck!
