Internships are usually paid or unpaid work experiences related to a student's major or field of interest. They provide an opportunity for students to gain hands-on experience in a professional setting, and to build skills and gain knowledge in their chosen field. Internships can be full-time or part-time and may be either paid or unpaid. Internships are typically completed over a semester or summer and may involve working with a company or organization on a specific project or task.
