Interview nerves, what actually helps? - first time posting

I have an interview on Friday and my stomach is in knots. There are 4 people counting on me, so I am trying to be careful. The role is similar to my old job as a quality inspector. What calms you down?

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

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