In my experience, years playing has nothing to do with how great of a player someone is... there are hundreds of other factors.
Here's my advice...
Confidence outweighs complexity... so I would pick something you know in and out and backwards and forwards before I would pick something just because you think the difficulty will impress people. It will ALWAYS look better if you play a less difficult song with ease than if you struggle to play something incredibly difficult.
Smile... be calm... be confident without being smug. Be polite... listen to questions and have questions prepared in case you have the opportunity.
Don't try to impress... just be yourself.
If you don't get the gig after that, then it just wasn't meant to be... there's a reason for everything, and something just as good or better will come along eventually.
Good luck!
Well said.
