What does a Sales Marketing company do?

I am going into for a job interview in a few hours and I don’t even know what the company does. All I know is they are called F.P Marketing.

What do you think they do?

Here is the website:

It uses a lot of big words to say nothing at all.
Sounds like this place hires salespeople to sell WHATEVER IT CAN GET to businesses.
Probably straight commission and high turnover.
