Preparing for my first interview in 9 months, school bus driver here

I have an interview on Monday and my stomach is in knots. It has been a long 20 weeks. I want to come across as confident and honest. How do you prepare answers?

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

Thanks for writing this out. I went through something close to it last year, and it settled down once I kept a simple log of every call and form.
