Well you can never be too prepared I suppose. Does anyone have any experience of the technical questions? I thought they would be more to do with the general physics of flight.
As for me so far I've studied (in relation to partner airlines) hubs, fleet with engine types, CEO and notable people, focus cities, future development, stock price and recent history, the mergers, Airline history and route map.
I'm not too sure what to study technically though, I read the book
Understanding Flight by David F. Anderson and Scott Eberhardt which I found to be excellent in explaining every aspect of flight.
