Your resume is arguable the single most important part of the application process. A well-organized, relevant resume will set you up to get an interview, while a poor resume will get completely lost in the sea of applicants. This is a fairly modern concern, as job postings now get thousands of online applications a day.
Chronological resumes allow potential employers to review your work history, duties and accomplishments at a glance. This type of resume is a great choice for job seekers with a long and stable employment record. Many hiring managers prefer seeing this traditional resume style.
