Real Eating Company interview questions

I went in and told the staff I was there for an interview. Nobody told me where to go so I sat down as the interviewer was with another person. None of the staff told the interview that I was there waiting so when he finished with the last person he just went off and did something else. I tried to catch his eye because I didn't know that he wasn't informed that I was there. After he came back I went over and introduced myself and then the interview took place. The interview was quite hard but relevant for the role.
