Zoom Interview Scam

I got a text asking when a good time for a zoom meeting is. We set it up. The next day I log onto Zoom and it’s a group interview for the first round. They asked why I’d be a good fit etc. They asked for no personal information at all. I called their company number I found on Google and they said the interview was legit and so was the person who interviewed me. Regardless, I think something is fishy. Maybe a pyramid scheme? Can they get anything important from me if I gave them nothing and only joined their zoom meeting?
