Chipotle interview questions

After applying online, I received an email saying that I had an interview about 3 days from then. I went to the interview and when i arrived there, me along with about 6 other people went through a group interview being asked standard questions. I then got a second interview which happened to be another group interview but with only 2 more people, and the last interview was ANOTHER group interview with about 4 other people. The fact that I had to go through 3 group interviews and study packets they gave me for the interviews made me think that they're doing a little too much as for a fast food restaurant goes. I guess they really want people that look dedicated and willing to go the extra mile.
