Georgetown University interview

My daughter had Georgetown University alumni interview today but I don’t think it went well.
First of all, I got lost so we were a couple minutes late getting there. My daughter brought her sister and a friend with her. They were jaywalking screaming and they found a interviewer standing outside of the starbucks.
They were sitting outside of the satrbucks for interview and her sister and a friend were inside watching them.
My daughter brought her sister because she was uncomfortable to meet someone at the coffee shop but that was big mistakes. He asked her sister inside the coffee shop made face at her? I think she failed the interview. How important is interview for admission?
