The purpose of an internship is also to help you make useful connections. The person or people who manage you during your internship may become mentors, who can provide helpful information and who can help guide you during your career. You can use them as references for future jobs, because they have seen you in action and they know your competencies.
In some cases, an internship can even lead to a permanent position. Many companies bring on some of the interns they’ve used and hire them for full-time positions, provided they have available positions. Once a company knows you and sees that you’re interested in a job and you’re skilled, they are more likely to hire you for their team.
You can do one or several internships to explore if a career is right for you. The more internships you do, the more experience, skills, confidence and connections you gain. These can all put you ahead of the curve when entering a job market, whether right out of school or when switching careers.
