What are the clever, resourceful, and truly evil recruiters doing? I guess the amateur ones can filter by universities and organizations, but surely there's a more efficient way to wade through the swamp of linkedin?
I guess I don't see being clever and resourceful synonymous with being evil. I don't know what the other guys are doing, but I try to use LinkedIn only as a reference (e.g. "where is this person working now, and how long have they been there?", "what kind of stuff has this person worked on historically?")
I try to look at blogs, GitHub, dribbble, HN posts, tweets, Quora submissions, and whatever else I can to try to get some idea of what the person in question is interested in and good at. At the end of the day, I'm trying to surface smart people. Then I try to figure out whether I can offer said smart people interesting work that's in line with what they seem to be passionate about.
