Employers don't consider your resume follow-up a waste of their time. While there will always be potential employers who are firm believers in the "don't call us, we'll call you" approach, most recruiters admire candidates who make an ef fort to follow up on their resumes. Follow-up shows both initiative and persistence, traits good managers love, especially in individuals who are applying for positions with major responsibilities. Don't worry about seeming too enthusiastic. Company representatives enjoy being pursued. It massages their egos and reminds them their company is worth courting.
