Preparing for my first interview in 4 months

It has been 4 months since my last interview and I feel rusty. There are 9 people counting on me, so I am trying to be careful. I have practised answers but they sound stiff. How do you prepare answers?

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

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