Always write a cover letter from scratch. I am a first-year law student at Harvard Law School and am writing to apply for a volunteer summer internship at your office.Learn how to write effective resumes and cover letters, view sample resumes and cover letters, and get tips for completing job applications. The best cover letters effectively communicate the candidate's qualifications, enthusiasm, and fit for the role. A reader just sent me a cover letter that I can't resist posting, especially because it comes with a "before" version and the "after" version she created. Your cover letter should articulate your qualifications and motivation for the position. Read the job description closely and research the organization. In applying for any open position, please follow the directions given at the bottom of the job description (cover letter, resume, etc.). I'm going to share with you the three part structure to create a bulletproof cover letter that gets you more interviews.
