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.
For each internship or job, include the name of the organization where you were employed, the city and state, the title of the positions held, the employment period for each job (include both months and years), and a short description of your accomplishments and technical skills used, listed in 3-4 max bullet points.
