Rightpoint Associate Experiece Design Director interview questions

Was asked to complete a complete client presentation including how I would implement the project, cost and timeline etc. I did well on that part and was told it was the best presentation they had ever seen. But once I asked for food after the extensive grilling on this presentation (which I didn't mind), it seemed to go down hill I don't know why they got a "bad vibe" I was hungry and went a little rapid fire with the HR guy when he asked me to recap everything I had gone over with three other sets of people.
