Short and to the point. They seemed quite excited and it seemed like it could be cool. I was offered the internship a couple days after I interviewed, and I accepted.
Super easy! Was just a quick phone call. Asked a few basic questions about background and experience. Didn't take very long at all. Asked if I had questions for her and that was it!
I was asked to tell a little about myself and then told about the position. The interviewers were friendly and personable. The interview was held over Zoom, and didn't last more than 15 minutes.
