If you’ve never created a technical presentation then let me help you understand what you are missing. Imagine writing a term paper like you did in college, except that the content is all in PowerPoint and SQL scripts. And your head. Mostly in your head, because you have to verbally speak way beyond what’s written down in slides and scripts. And it has to be an hour’s worth of material. And this will all be done in front of a roomful of strangers. Strangers who get to ask you random questions at random times.
