Some companies will indicate that they want you to submit a CV rather than a resume. A CV and a resume are not the same. CV stands for “curriculum vitae” and is meant to be an expansion of your resume. It is much longer than a resume, often three pages or more, and focuses mainly on your academic and professional accomplishments, with a particular focus on education.
When you’re working on your brain dump, make sure to include the name of the company, its location, dates of employment, and several bullet points describing your role and responsibilities for each position you list. Although you may need to expand on the bullet points later on, you’ll need this information at the minimum.
