The purpose of a cover letter is to link your resume to the open position & is a standard document which is often requested along with your resume when applying for a job. Employers use cover letters to assess writing skills, determine attention to detail & discern how past performance & experience connects with the job responsibilities.
You may use your resume contact heading to create a professional letterhead.
Use the same font and text size as your resume.
Keep the letter to one page.
Reference the job and/or job number on a subject line.
The salutation should include the hiring or recruiting manager's name. If you're not aware of who will be receiving your cover letter and resume, you can reference a department or the organization itself. (Do not use: "To Whom it May Concern.")
The opening paragraph should clearly state the reason for the letter. Ask yourself, "What is my objective?" and use your answer to craft your first remarks.
Explain why you're interested in the position and why you're a good fit for the company based on information in the job posting. Review the organization's website and pick out something that resonates with you. Take a look at their mission and vision, company values, latest PR announcement, or a new product or service offering. Reference such information in this second paragraph as it applies to potential contributions you could make if hired for the job. Look also for specific needs or "pain points" within the organization. How can you help to meet those?
The third paragraph should directly tie your qualifications to the requirements of the position. Select three or four requirements from the job posting and link your qualifications, specific job skills, and/or experience to each in a conversational way. For example, if one of the job requirements is, "Manages a sales team of four," a sample sentence might read, "With two years of experience in Customer Service, I became proficient in organizational dynamics which would serve to enhance my ability to manage a team."
Summarize your objective and express your gratitude for the opportunity to apply. A good rule of thumb is to thank the reader for his/her time and consideration, and to invite a reply. For example: "I appreciate your time in reviewing these credentials and the attached resume. Thank you for your consideration, and I look forward to hearing from you soon."
Finally, include a professional valediction with your name and contact information (if not included in the letterhead). Common choices include "Regards," "Thank you," and "Cordially."
