Hitting your peak in the interview itself is grounded in making the preparations that work for you. It is intensely individual. Some will improve through rehearsing responses to questions fired at them, for others that augurs sounding over prepared and stilted. What just about everyone can benefit from, is talking about something that energises or drives them about their topic just before the interview starts. It warms you up before you turn to that laptop lens, even if only that wall in the spare room is listening. Presenters and audiences alike warm to spikes of colour, of compelling detail, and you’ll more likely to deliver that colour if those words have just been articulated.
