Definitely take notes and a have a few questions jotted down before you go in. It shows that you're interested, proffessional, and organized - all good qualities.

Also think about a few difficult situations you've had a jobs in the past, and how you handled them. It seems like interviewers (especially in large corporations) always ask questions like:

"Tell us about a time when you had to deal with an irate client and how you handled it."
or
"Give us an example of a situation in which you were forced to learn a new skillset in order to complete the task assigned to you."

I always seem to get these types of questions.
