There is one type of business presentation that some people have to go through and in some ways, it is the hardest presentation they will ever give. On the other hand, it is also the easiest presentation that they will ever give. I am talking about the one on one presentation. There is no lectern or spotlight or powerpoint- you are just talking to one other person.
It seems easy in theory because there is no crowd watching you or slides behind you. You can just make conversation with the person in front of you. However, there is still the danger that exists with presentations: you could speak and the other person could remember nothing. And if they do not remember your message, how can they take action?
It does not matter if it is a ob interview or a pitch for a new business. Chances are that the person has probably heard presentations from your competitors as well. The danger is not that you may make a bad impression but it is that you may make no impression. So I believe that you should go into a one on one presentation with the same preparation with which you would go into a so called big hour long powerpoint presentation.
You need to have a clear perception of what your messages are, you should have prepared on video beforehand, but you should also not have a bunch of notes in your hand. You need to figure out what it is that would motivate this person to hire you or sign you on.
