Earlier quoted context omitted.
I make it a point to not read resumes unless I'm supposed to be asking questions about their contents, to avoid bias.
To avoid bias? As in to be completely unprepared? Wouldn't reading the résumé give you a better idea of the interviewee's background, and allow you to better assess him?
(Not trying to claim that I'm actually able to figure out much of anything in a technical interview, but that's the goal.)
