ABC published an article on job search tips with advice from Angela Copeland, Recruiter.com VP of Marketing.
"... try to figure out the title of the person you would be reporting to based on the title you are applying for, recommended Angela Copeland, vice president of marketing at Recruiter.com.
“Let’s say it’s marketing director — think of the hierarchy of a company: you will typically report into the vice president, or if you are manager you might report into the director. You can look on the company’s LinkedIn page to see employees and filter down by job title.”
If this still brings up too many potential results, Copeland suggested scanning the job posting for more clues. “Look for something unique in the job description that you would be doing that your hiring manager might also know about and put that in as a keyword … to help you narrow it down.”
