How often do people recruit through cold-calls anymore? I was at one of the companies mentioned, and was contacted by a recruiter from another one of the companies menteioned, but they contacted me through linked-in, not through a cold-call. Did the agreement really matter anymore with all the alternative ways of communicating? (I ended up leaving where I was, but didn't go to the place that was recruiting me.)
