Interview nerves, what actually helps?, social media manager here

I have an interview on Monday and my stomach is in knots. I have practised answers but they sound stiff. Any questions to ask at the end?

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 last year, and it settled down once I kept a simple log of every call and form.
