Jobs vs. Internships vs. Careers: What's the Difference?
A job is something you do for money. They can be long-term or short-term, high-paying or low-paying, seasonal or full-time. There is a wide variety of jobs available, and most people will have many across their lifetime. An internship is a type of job that is built to be a learning experience. There is often a set end date, and built in learning and supervision throughout.
A career is the summation of your professional journey, including things like your education, work experience, volunteering, etc. It is a lifelong path, with no real beginning or end.
