Of course. Out of my 6 or so jobs in 3 1/2 years I think the first one was the only one gotten that way. I think there was another one where the hiring manager found me on a job board, if that counts. The others - and everything that's happened since in the consulting world for me - are all predicated on relationships build in the course of working, as well as being socially involved in the discursive space of my profession.
