How many internships do I need to ensure that I get a job after graduation?

I’m a junior in college and I had an internship during the summer going into junior year. My internship during the summer was unpaid and I mostly did busy work. I just accepted an offer with a paid internship with a stipend for my spring semester of junior year. I don’t know whether I should get another internship, but I know I would rather work a regular job to earn extra money. What should I do to make sure I’m being marketable?
