This document discusses different types of job application letters. There are three main types: 1) Letter style applications which include biographical information, qualifications, experience, and references. 2) Prescribed forms required by some employers which standardize information for easy comparison. 3) Cover letters submitted with resumes, which highlight relevance to the specific position. Resumes can be chronological, listing employment history, or functional, focusing on skills. A curriculum vitae (CV) provides more details on personal and professional background than a resume.
