I freeze in interviews, tips? - first time posting

I have an interview on Wednesday and my stomach is in knots. I have been trying to stay organised about it. The role is similar to my old job as an event coordinator. Any questions to ask at the end?

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

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