luxe collective group interview questions

I applied for the position after learning about it through a connection in a LinkedIn group. They called me about two weeks later asking me to come to NY for an interview. I drove the 8 hrs to NY and the interview lasted fifteen minutes. I was interviewed by two entry-level Assistant Media Planners, the same position I was applying for. No difficult questions. The interview went as well as a fifteen minute interview can go, however they never contacted me afterwards. I called and emailed them numerous times in the weeks following the interview and they never responded. Two months later I emailed them yet again, and they finally replied stating that the job had been filled.
