I know this will sound crazy, but I know at the end of the resume you always find "references available upon request." I have never been actually asked for references, but how do you list them? Is there a certain format you use? Do you keep a copy of your references when you go on interviews just in case they are requested? I usually have my references listed and kept in the very back of my portfolio, just in case I am asked, but I was wondering how others approach this!
