Like a powerful résumé and a good business suit, the cover letter is fast becoming indispensable in the job search. Perhaps no other single question is heard so frequently by career professionals… "Do I need a cover letter?"
The answer is a resounding Yes! A cover letter is an essentially a brief letter accompanying your résumé which first and foremost asks prospective employers to take their valuable time to read your résumé.
Ideally, your cover letter should match your résumé in format. It should be neither too short (one paragraph) or too long (most all of a page or more than a page). When at all possible, your cover letter should specify the date, as well as the name, title, company, department, and address of the individual for whom it is intended.
