Since my job search is going so poorly, I was wondering how effective it is to identify a number of places you want to work at, identifying who the hiring person is, and then sending them a resume and cover letter, even though no job is being advertised. The cover letter would describe why you want to work there and what you have to offer the organization. I was under the impression that for public agencies, this tactic is pointless since they have to give everyone a fair chance. It might work better at a private firm, but I don't know. Anyways, does this tactic work?
