As with resumes, your cover letter should only be one page. Talk about the achievements you are most proud of, not every detail of your previous job. You want to hold the attention of the employer and make him or her want to learn more about you.
Get your dream job Chances are your first job will not be your dream job, but one of many as you work your way to the top. Know what your career goals are and talk to other professionals so that you know what steps to take to obtain your dream job.
