Interview nerves, what actually helps? (Little Rock)

I have an interview on Monday and my stomach is in knots. I want to come across as confident and honest. How do you prepare answers?

I record myself on my phone and listen back. The second try is always better than the first.

Thanks for writing this out. I went through something close to it 12 months ago, and it got easier once I kept a simple log of every call and form.
