Since Thanksgiving I have gotten three interviews from Craigslist, one phone interview and two face-to-face interviews. All legitimate.
In all three cases the hiring companies wanted to maintain confidentiality for one reason or another. These were real professional jobs, not fishing expeditions.
I have solicited resumes through newspapers at different times, received blind resumes, gotten unwanted referrals from customers, suppliers, and of course, relatives and friends of the boss(es) and owners.
Most replies to classified ads, whether in the newspaper as we did back in the day,.
Monster, Career Builders, Craigslist and direct-applications to companies through their websites, generate lots of inappropriate responses. My favorite was about 25 years ago when I advertised for a legal secretary for a boutique type law firm and I received a resume from a guy in a hematology lab who spent his days doing cell counts.
It is part of the process. You have to slog through the pile of resumes, culling out the ones who haven’t got a prayer of getting an interview and finding the ones that might work out.
