Recruiters sometimes get a bad rap, kind of like salespeople.
We are really here to do our job, just like anyone else. As in any profession, there are good apples and, unfortunately, some who are not.
I do my fair share of cold-calling when I am working on a new position. Many people I contact are open to conversation, others not as much. Breaking through the suspicion of recruiters is important to a worthwhile exchange. When a recruiter calls, keep in mind that your willingness to listen to new opportunities for a few minutes could lead to great things.
