A resume is a one-page document that highlights your background, skills, and experiences. It shows your "personal brand" to a potential employer.A curriculum vitae or CV is very similar to a resume but more comprehensive and often multiple pages. It is often used in academia and science fields. The application is considered a document certifying your background and allows you to give the employer other info they need for hiring purposes. Include anything relevant to the role – paid or unpaid, part-time or full-time. I am a huge proponent of following up immediately after you've put in your application.
