Caltech (California) Events Assistant interview questions

3 hours of round after round of interviews that would end with me having nothing else to say an awkward moment of being asked "Do you have any more questions?" The interview began with an awkward unexpected luncheon with 3 other ladies on the team. Then it was followed but meeting more and more key people from different departments and they all had less to say and expected me to have more to say about myself. It was both casual and formal at the same time. A person was assigned to me to tour me through the interview process and I had no idea I'd be meeting with over 10 people in one day and did not know it would start with a lunch. That should have made it easier but it just made it harder.
