Wasting your and my time

I had a really interesting experience recently which I hope might enlighten others as much as it did me: I was approached (via LinkedIn) by a recruiter from one of the big tech firms, as they put it "based on the work you've been publishing on image analysis and learning models".  I would have to admit that doing this kind of work for one of the holy trinity sounds like a dream job for a hardcore geek like myself.
