Macy's Retail Support Associate, Flex Team interview questions

I applied online, and received email two days later saying i was invited to schedule an interview. I scheduled the interview for two after i received the invite email. I showed up to my interview about 20 mins early, went to the office and waited about 10mins for the interviewer to come. Interviewer was seemingly friendly, asked me to tell him about myself then asked about my availability, upon telling him i would have a seasonal commitment and would have to leave toward the end of August to go back to school , he pretty much just shut down which was very awkward, pretty abruptly told me they were only looking for people with a longer term commitment, then stood up and said thanks for coming (this all occurred literally in the span of about 4-5 mins)
