I freeze in interviews, tips? - 23 weeks in

I have an interview on Wednesday and my stomach is in knots. This is my first time dealing with any of this. The role is similar to my old job as a customer-service rep. Any questions to ask at the end?

Thanks for writing this out. I went through something close to it 7 months ago, and it got easier once I kept a simple log of every call and form.

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