Carmazzi Global Solutions interview questions

It was incredibly short. I was briefly asked to tell a little about myself, then briefly told about the position. At this point, I acknowledged I would be having some college classes on certain days during the day, at which point the interview was suddenly shut down and I was flat out rejected. The ironic thing is, I found this job opening through my college's job board for employers that are willing to hire students, so I don't understand the basis for this decision. It seems like the company is not being sincere about its offering, and that this was just a big waste of my time. They should rethink the listing on the college job board if they're not serious rather than waste students' valuable time.
