You want to work in industry
Career development during graduate school is similar to the undergraduate process. As an MS or PhD student, your résumé can be very much the same as your undergraduate résumé. Focus on details about the work you’ve done that translates to the work your potential employer wants you to do. This includes professional experience, internships and co-ops, research and hands-on projects. Because you’ve done more than an undergraduate student, it’s perfectly acceptable that your résumé become two pages.
Doctoral students interested in working in academia will develop a curriculum vitae, or CV, highlighting previous academic experience (research, publications, and teaching experience). Curriculum vitae are typically much longer than résumés.
