I freeze in interviews, tips? - 23 weeks in

I have an interview on Tuesday and my stomach is in knots. There are 7 people counting on me, so I am trying to be careful. The role is similar to my old job as a home health aide. How do you prepare answers?

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

Keep everything in writing and save the confirmation numbers. It made the follow-up calls so much easier.
