I will agree 100% regarding the job postings. 'Carpet bombing' companies rarely works. However the same doesn't always apply to dealing a recruiters and/or friends, your reality isn't everyones.

I'm only expressing that there is validity to not narrowing your interests, fields or industries and that dismissing someone out of hand because they are 'unfocused' is just as bad and unhelpful as dismissing someone because they don't have a degree. (an entirely different conversation)
