Here's my best guess given what you wrote. The company felt that you were good enough to be an intern there. They also had other candidates that they thought would be better. They only take n interns a year. That started from the best candidates and worked there way down until they got n yeses. Once you graduate this will be less of a problem. Most big companies are always hiring. If they like you they'll make an offer. This can still be a problem at smaller companies though. If they only have one or two positions to fill they'll usually tend to be pickier.
