How useful are cold calls in an effective job search?
Making cold calls and sending out cold resumes is such a long shot. Why not spend just 5% of your job search time on that and spend the rest of the time on smarter networking and cultivation of contacts.
Hirers will receive so many cold resumes – they are most likely in the end to hire someone that has been referred to them. So your time is better spent ginning up those referrals for yourself.
