Competitive Consulting interview questions

After submitting my application via email, I recieved a call the very next day. I went to the initial interview, filled out a questionaire, and met with a representative who asked if I would like to come back tomorrow. The next day consisted of a day long interview. 9 to 6 pm out in the field. It is a sales position. We returned and I thought I would get to go home, but was interviewed by the main manager when I was extremely tired. He asked if I wanted to come back tomorrow and sit in on one of the meetings. I slept on it, and just went to my original job instead.
