If you plan to apply for or send a general inquiry regarding a job, at some point you must write either a cover letter or letter of intent. The cover letter and letter of intent are similar, but the purpose behind each type of communication and content is a bit different.
Letter of Intent
Identify the purpose of your letter, which is to express your interest in becoming employed at the company. If someone has referred you to the organization, say so in the first paragraph of your letter.
Describe your background, education and skills briefly. This way the hiring manager can get an idea of the positions at the company that would suit you.
Inquire about open positions at the firm. Ask the hiring manager to contact you via phone or email if a position is available. If yes, you can then proceed to send a full resume and cover letter to the firm.
Inform the hiring manager in the first lines that you’re applying for the open position at the firm that you’ve identified. Explain that you feel your qualifications fit the position and why you want to work for the firm. Mention the person who referred you, if applicable.
Identify your skills, training and qualifications for the position briefly in the next paragraph. The second paragraph of the cover letter is a quick summary of what the employer can expect when he reads your resume that highlights your best attributes.
Close your cover letter by reiterating to the hiring manager why you’re qualified for this open position. Ask the manager to accept your resume for consideration and contact you for an interview. Provide your phone number and email address before signing off.
