But do include enough tidbits to generate interest in the mind of the reader. Show your enthusiasm about the job. State that you will follow up to schedule an interview. If you politely inform the reader that you'll be calling within a few days to answer any questions and schedule an in-person interview, you set yourself apart from the crowd with your determination and confidence. Keep your letter short and focused.
Most letters ramble on in excruciating detail for one or even two full pages.
Show respect for the limited time your reader has and limit yourself to four, five or six paragraphs at most. Say why you are interested in this organization, and why you think you are a good fit for this job. Tailor the letter to the requirements described in the ad. It is important to include information not on your r sum such as additional accomplishments germane to this job. If you literally mean you are being asked to provide a letter of interest with an employment application, and don't have a job description or list of qualifications, you can't be so specific.
