Phone screen booked, I am thrilled (update)

After 17 applications I finally got a call for an interview as a welding apprentice. There are 17 people counting on me, so I am trying to be careful. I have not been this excited in months. Any last-minute tips?

Thanks for writing this out. I went through something close to it 13 months ago, and it settled down once I kept a simple log of every call and form.
