About this skill

About Cover letter writer

Cover letters that repeat the resume don't get read past the first line. This skill writes a letter of 250 words or fewer that opens with a specific reason you want this company and role, proves fit with two achievements that match the job's top needs, shows how you'd add value early on and closes with a confident ask. It avoids clichés like 'I am writing to apply' and never invents experience. It also explains why it chose those two stories. To use it, paste the skill into your assistant and send the job description, your resume and one reason you want this job; the reply opens with “Cover letter”.
