Interview nerves, what actually helps?, recruiter here

I have an interview on Thursday and my stomach is in knots. I would rather hear the honest version than the polite one. 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 10 months ago, and it got easier once I kept a simple log of every call and form.
