How Is A Resume Different From A Cover Letter. In contrast, a cover letter provides an opportunity to explain why you are qualified for the job. A letter of interest is used to express interest in working at a company that isn’t necessarily hiring.

For this reason, it is a good idea to enclose a cover letter in addition to a resume when applying for a job. The goal of a cover letter is to convince employers that you’re interested in and qualified for a job. Resumes are a requirement when you apply for work.
