Interview nerves, what actually helps? - any advice?

I get tongue-tied when I am asked about my weaknesses. This is my first time dealing with any of this. The role is similar to my old job as an HR coordinator. How do you prepare answers?

Keep everything in writing and save the confirmation numbers. It saved me later.

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