Do a lot of research on the company, try and aim to know more than the interviewer about the history and goals of the company if it's a huge corporation.
If you have the names of the interviewers then research them, find their linkedin profiles (setup a new dummy anon linkedin profile for linkedin stalking). You'd be surprised how much you can both put yourself at ease and be on the front foot by simply knowing who's going to be interviewing you.
Take notes, it doesn't matter if you can't read them. Taking notes is universally accepted as something that's a good quality, even if you're not a note taker. It just shows organisation and the an awareness of what is being said to you, especially when you're asking the questions. It also gives you a distraction, and a shield (holding a pen, having paper in front of you, these things help you in confidence, it's a better 'stance' to be in than arms by your side being fired questions).
Overall the best thing you can do is surprise them, go out of your way to estimate what they're going to be asking and what they'll be interested in and find something that they can relate to and will be impressed by. I remember one of my interviews, in the first of two interviews one of the HR directors asked me if I think it would be possible to create a solution on one of their systems to a problem they've been having. When I came back for my second interview I had outlined several different options for them to achieve a solution to the problem they were facing. I wasn't asked to do it, but their faces lit up when I started talking about it. In another interview I took a portfolio of some of the big projects I'd worked on in the past and made 3 copies of it for my interviewers.
Try and make an impact by being a little innovative and you won't be forgotten, and when it comes to discussing the best candidate you'll be in the front of their mind.
