The interview was a breeze, they never asked me anything-but asked my husband everything-took all the docs...financial evidence...birth..marriage...police...no need for xpress post (i wasted 12 bucks) sign up for DHL
Philandjulie-follow the Interview Prep Link on the state.gov website...you will be directed to the DHL website...where you have to sign up for it and they ask you which DHL location you would like to get your passport from...so you select whichever is closest...hope this helps.
