On the flip side, I do technical interviews (I am new to it though), and I spend about half an hour preparing for an interview including going through the CV that made it to me (and making notes/preparing questions) and researching the candidate based on what I see in it (e.g following links, etc)
I do the same thing. The CV is typically made available to me a couple of days before the interview, and I usually take a look at it the day before. Obviously I can't really know how carefully it gets scanned before they decide to arrange the technical interview (which is where I step in).
