When you work as an intern, there’s a decent chance that you might not end up liking your job. And that’s just fine. Part of the internship experience is finding out if you really want to turn a job into a career.
There’s a reason why so many students change their major. Some even do it a few times. It’s difficult to pick a subject and dedicate your life to it. Sometimes students discover that they don’t want to continue down that road when they take certain classes.
