I freeze in interviews, tips? after 15 years as a home health aide

It has been 7 months since my last interview and I feel rusty. There are 15 people counting on me, so I am trying to be careful. I have practised answers but they sound stiff. 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.
