Interview or not?

Hi all,

I have been mass applying for internships going into my junior year in college and just received an email from northwestern mutual that says "You applied to an opening for our internship program. If you are still interested currently, let’s schedule some time to talk. What does your availability look like for this week or next week?" is this an interview or just a quick chat? how do I even prep for something like this? Thank you for any help
