People perceive people who ask questions to be more intelligent than someone who doesn't ask questions. In my business I make a habit of asking questions: why people did something, why they did a certain way, etc. Halfway through my barrage of questions, they always stop to ask what it is I know.

Once that happens, I get repositioned as an expert in my field. Point for me.
Now I don't interview much anymore; ever, but you can use the same tactics to make yourself look good.
If you wait until the end and ask the same lame questions that everyone else does, then you're like everyone else.
When I used interview, I tried to interview the interviewer. I ask them all kinds of questions, but not before they ask me a few questions. I ask people if they like their job. I might ask them if they like working there or what they don't like about working there. I ask them if they'd recommend their employer to a friend. I ask them if they use the services of their own company, if they market a product or service that the consumer uses. If they do or don't, I ask them why.
This always catches them off guard. And at some point they'll ask why I want to know all these things. I tell them that just like they are interviewing me that I am interviewing them. I explain that I want to make sure that if I am offered a position that this is a place I want to work for. That always blows them away.
They held all the power; the job over me. Now I just told them I don't care if they offer the job, because I might not take it. While they don't know what it is I'm after, they now know that I know enough to pick and choose from the best. They also then assume as a result of me taking that angle, that I am someone who is good enough to have my choice of places to work from.
It's all about positioning; positioning yourself from the other people.
Good luck.
