Many individuals search the "want ads" for job openings. Although this is not the best method for identifying job leads, it can be helpful for some types of jobs, particularly entry-level positions. To use ads effectively, however, you must understand that it is still your responsibility to follow up with an employer when you submit a resume in response to a classified ad. You should call within a few days of mailing the resume to see if you can arrange for an interview. This intensive follow-up demonstrates to the employer that you are truly interested in the job and makes it more likely that you will be invited for an interview.
