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.
Ultimately, you want to try to strike a balance between including experience that is both timely and relevant. There are several basic types of resumes used to apply for job openings. Before you spend time writing up all the details around each position you’ve had, you should decide what style of resume to use, as that can affect how you describe, organize, and list your experience, education, skills, qualifications, and other credentials for employment.
