I stumbled across this character sheet created by Fancy We got this and you don't have to download it unless you want to.
this is a very very extensive character interview sheet. It comes to us from the creators of the NaNoWriMo

2743195 This is the item number.
You can find it if you go to the 2015 Calendar, click on the Protagonist Assignment for day 2. You will find the actual link to the page on WDC I am still learning how to link things on this website. Not good yet but I am trying to get there.
I hope it helps. I know it will help me to figure some things out about my already existing characters.
