Heather Hilliard Design interview questions

I applied online for the position and was contacted for an interview. They had an allotted interview time and half hour for a CAD test. They were four women working in an open space. They seemed like nice people and the interview was not as stressful as other interviews. I got the vibe they were genuinely very convivial and wanted someone that fit into their group, more than it was about skills. They never responded to me again, even a after following up with them. I think it's very unprofessional that they would take the time to talk to you, ask you to do a cad test, and not even thank you or tell you they went with someone else.
