Interview nerves, what actually helps? - 8 weeks in

I have an interview on Wednesday and my stomach is in knots. I want to come across as confident and honest. What calms you down?

Arrive early, drink water and take a slow breath before you walk in. It sounds simple but it helps.

Thanks for writing this out. I went through something close to it 7 months ago, and it settled down once I kept a simple log of every call and form.
