I freeze in interviews, tips?

It has been 8 months since my last interview and I feel rusty. This is my first time dealing with any of this. The role is similar to my old job as an administrative assistant. Any questions to ask at the end?

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

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