If a company hires us for a social engineering engagement, typically they want us to get in and get to their back-up tapes, or into the data in their document room.
Let's say I am posing as a fire inspector. The first thing I will have besides my badge and uniform is a walkie-talkie, like all firemen. Outside, we'll have our car guy. The guy that sits in the car, and basically his job in the beginning is to send chatter through to our walkie-talkies. We will have a recording of all that chatter you'll hear on walkie-talkies. He sits in the car and plays it and sends it through to our walkie-talkies.

I stay with the person who is escorting me and my whole job now is keeping them entertained. I keep walking around rooms, giving them advice on keeping their facility fire safe, even though I really have no idea what I'm talking about. I make stuff up and probably give the worst advice ever. I'll pull out cords and say "This looks a little bit dangerous." I'll comment on space heaters. I'm completely winging it.
