A letter of interest, also called a prospecting letter, is a type of cover letter, which is usually attached with your resume to apply for a job. It is written to express your interest to work for a company in a particular field. It is a golden opportunity for you to make a good impression on a prospective employer. You can write a letter of interest to respond to a job opening or to investigate an employment opportunity.
Call the company and ask them the name of the person doing the hiring. Address your letter to him. Do not write "Dear Sir/Madam" and "To whom it may concern," as they are both outdated and considered unprofessional.
Conduct research about the company. Check the company's website, annual report, the job profile offered, etc., to make yourself familiar with the products and services offered by the company.
Catch the attention of your employer by stating the reason of your interest for the particular job and how you fit for the job. Do not start your first sentence with "I". Also, state the reference from where you get the information about the job, like a media article, classified advertisement, a referral from an employee, etc.
Quote specific examples of your professional and educational qualifications. Illustrate your strengths, skills, and achievements in a professional, yet pleasant way, so that the employer can become interested enough to read your resume. Keep the letter to one page.
Include a paragraph thanking the reader at the end of the letter. Thank the individual for their time. Indicate when you will contact the employer to follow up. Provide your full contact information, so that the employer can contact you any time he wants.
Include contact information of the company and the current date at the top of the letter. Type the letter on Microsoft Word and check for any spelling or grammatical mistakes. Your letter should be errorless. In the end, get the printout, sign it and send along with your resume.
