There are reasons why recruiters or hiring managers do not call back some job seekers: blacklists! In today’s tough job market, desperate job seekers are pursuing what little jobs are available. Hiring managers have plenty of applicants to choose from, so they are justifiably selective and quick to record any negatives they discover. If you are blacklisted, recruiters do not submit you to jobs today, even years from now. Even if you are not on an actual “list”, recruiters do remember if you left a bad impression. They also pass the word along to fellow recruiters, and they remember bad candidates even if they change companies.
