Well, I have written at length throughout this thread on things I like to see....preparation being a good starting point.
To be honest, the other areas we look for are characteristics that you either have or you don't have.
I don't think that the interviews we run are any different to any other, so the sort of things every interview candidate should be doing before an interview will stand you in good stead......doesn't mean you'll be successful of course, I could be faced with the best prepared candidate in the world but (s)he might not get through because of other factors.
