For an internship, no experience is mandatory for most roles. Most companies still expect you to have some experience or familiarity with their tools or industry, but professional experience is unnecessary. For example, if you're working as a customer experience intern, companies may expect you to have some familiarity with designing training portfolios and standard office software. As a student and intern, your main job is to go through the companies internship program and gain credit towards graduation or experience for your resume. These internships are always temporary assignments, usually lasting three to six months, but some employers are willing to hire anyone who does well during the program.
