What is the function of a cover letter?

The primary function of a cover letter is to introduce oneself and explain interest in a job position. It serves as a personal communication tool that allows the applicant to present their qualifications, experiences, and enthusiasm for the specific role they are applying for, going beyond just listing facts found in a resume. The cover letter typically provides context for the resume, helping to establish a connection between the applicant's skills and the needs of the company. This personal touch can make a significant impact on hiring managers, as it gives insight into the applicant's personality and motivation.

The other options are important aspects of the job application process but are not the central purpose of a cover letter. Summarizing resume details, providing references, or outlining salary expectations can be addressed in different formats or sections of the application process, but the cover letter's distinct role is to facilitate an introduction and express specific interest in the job at hand.
