Preparing for my first interview in 12 months - what worked for you?

It has been 12 months since my last interview and I feel rusty. I worked as a procurement assistant before this. I have practised answers but they sound stiff. 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.
