What should the main points of your letter be?
First, state the purpose of your letter, the type of job you are applying for and how you heard about the company. Second, briefly say why you are interested in the position and in the company. Include what you can offer in the way of educational/work experience. Third, thank the employer for taking the time to look over your resume. Mention that you will be the one to get in touch with them to answer any questions about your resume and find out if the employer has any further questions. End by saying you hope to speak with them again in the near future.
