References. It is assumed that you have references if you have previous employment history. It is not at all necessary to include “references available upon request”, adding this is actually a potential deterrent. Potential employers will ask you for your references later on in the interview process if they see fit. Of course, if references are asked for within the application process, provide them - just not on your resume.
No matter your approach, your goal will be to produce a chronological list of experience that is relevant to the jobs you’re applying to. Although this should focus on professional work experience, you can also include awards or accolades, volunteer or community experience, post-grad coursework, and skills, as well as your college education, which can move to the bottom of your resume once you get your first job after college.
