I hate to say this, but many recruiters who contact me seem to reside and work from India. I get all kinds of recruiter attention, including unsolicited emails, calls, and texts, but most of them seem to be looking for a relationship where I do the work, and they subcontract with a subcontractor who's subcontracting for another contract for a major firm. It's basically spam at this point. How can we "stand out" without getting bombarded with low-quality "proposals"?
