Preparing for my first interview in 2 months - any advice?

I have an interview on Monday and my stomach is in knots. This is my first time dealing with any of this. The role is similar to my old job as a paralegal. What calms you down?

Prepare three stories with a clear beginning, action and result, and adapt them to the questions.

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