Creating a professional resume is often touted as the most important part of the job application process, but the effect of a good cover letter should not be underestimated.Why Use A Cover Letter?A cover letter is a good way to infuse some personality into your job application. It is not a place to simply summarize the information on your resume. Instead, you should view your cover letter as a chance to let your personality shine through. A good cover can set your application apart from the pack and give your potential employer a reason to keep reason the rest of your application materials.What To IncludeIn your cover letter, strike a professional tone. Make sure you have someone you trust look over the finished product to ensure you don't have any spelling or grammar errors. Your cover letter is your chance to tell the story of your working life. Mention specific highlights of your career, but also touch on why you are applying for this particular job and how your specific experience is appropriate for this role. You are selling yourself, but you should also sell your specific skills in order to to make yourself attractive to a potential employer.What Not to IncludeBeware of being too personal or chatty in your cover letter. Also avoid sloppy editing that leaves simple spelling and grammar mistakes unchecked. Don't simply reword details from your resume into sentences and paragraphs; your employer may think that you lack the ability to reflect on your own work and educational experiences. Finally, try not to dwell too much on why you want this job. The focus should be on what you bring to this employer and not the other way around.As you prepare applications and resumes, do not disregard the importance of a strong cover letter. Print your final product on nice paper in a non-distracting white or cream color, and do your best to keep the font readable and plain. By following these steps, you're more likely to get that second look, and perhaps even a shot at your dream job.
