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.
Regardless of the type of resume you choose, aim to tailor your resume to the job you are applying to. While it’s perfectly acceptable to use a resume template, which you adapt to fit each job description, it’s a bad idea to send the same exact resume to multiple openings, even within the same field.
