Yes, this is advice not given from experience.
You'll want to try to do some homework on the company before you go; perhaps not to the level of "In 2006, your company shipped five thousand metric tons of widgets."
You might become familiar with what they do, where they're located, and perhaps some of the history of the company. Apply for a job at Unisys, for example, and you might throw out that Unisys was a merger of Burroughs and Sperry-Rand (I think) back in the mid-1980's.
You may certainly ask questions about the company. Asking questions shows interest in the company and position.
Try not to ask questions which reveal complete ingorance of the company, and I would say you won't usually have the chance to ask so many questions just to hide your deficiencies.
Some interviewers are less qualified than you, but you'll find most know the ropes, and they'll know when you're trying to "fake" them.
Yes, it is a game, and you will learn how it's played. (I'm not good at it.) You will learn how to "schmooze."
It might also very well be that your first interview will be the one which gets you hired.
