Phone screen booked, I am thrilled - any advice?

It took 21 weeks, but I have a first interview on Friday. I have read a lot of threads here and could not find my exact situation. They liked my volunteering experience. Any last-minute tips?

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.

Congratulations! That is great news. Prepare three stories and a couple of questions, and you will be fine.
