Not everyone gives Paxman such a hard time. In fact, I am not sure Paxo has ever had an interview as harsh (on him) as this one. This clip is ample evidence that knowing what you are talking about is a key to success. Paxman and Co can smell blaggers from a couple of miles off.
I worked with a newly appointed divisional CEO of a global PLC recently. We worked on content first, delivery and more later. Knowing your stuff is the corner stone that supports your entire performance – it enables you to deploy your arguments with conviction and without hesitation and focus ion your delivery and the audience/interrogators.
And it keeps you cool under fire!!!
