Before I address the main part of your question, I'll first say that I don't think there is only one right career path for us. I also think people can start on one career path and later down the road realize they want to do something else - and then they change their path. This can happen multiple times, or not at all.
A good way to know if you've chosen the "right" career path for you, for this time in your career/life, is to continuously assess how you feel about the career. Do you enjoy the work most of the time? Do you feel like you're continuing to grow, and learning new things? Do you feel challenged? Do you like the people you're working with and connect with the values? As long as you can mostly say "yes" to those questions, I think you're usually on the right path.

Alexi, this is a great question! I think the best way to find out is to try it, and try others, too. The best internships I had in college were the ones I didn't enjoy, so I knew I could cross them off the list.
