Which resume type should you use for your job search? That depends on what you are trying to accomplish. The goal of any resume is to show a hiring manager the applicants strengths, skills, and experience in as short a time as possible. According to one study, recruiters spend as little as six seconds reviewing a resume before moving on to the next, so it is in your best interests to put your finest qualities and accomplishments in a prominent position on the page.
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.
