Chipotle Entry-level Crew Food Service Position interview questions

Applied online, answered questions online such like this: why you want to work for Chipotle, what your goals and what you can bring to Chipotle. 2-3 weeks after submitted, they sent me an email to set up interview appointment and I replied and set up to show up at 11:00am and I showed up and there were nobody in the job fair event and only two people there to interview applicants and I was interviewed for 10 min then told me that will be in touch in a couple days. Two days after interview I received an email from Chipotle with no person name that wrote the email to me that they said I wasn't being selected for an offer for a position. No explanations at all! Very cold and unprofessional way to handle.
