I met two recruiters at my campus career fair. They invited me to interview with them the next day. The interview was fine, mostly background questions with some experience questions and a couple of scenario's to respond to. They also invited those who were interviewing for a position to dinner and treated us. They were friendly and made us feel welcome!
They'd already filled their internship positions, and they were interviewing us in case spots opened up, so no offer was made. There is a chance of an offer in the future.
Overall, a great experience!
