Scheduled a 30 minute phone interview that ended curtly after 15 minutes.

I was contacted by a placement agency for a full-time position at Vistage. Immediately I was scheduled a phone interview. I asked about the phone interview logistics and was told I would be called by the hiring manager. Scheduled 30 mins I was called ~ 15 minutes late and ended on-time. There was two people on the call but only one introduced herself. There were no introductions and the call started awkward. When I showed interest of the unique service line, I got crickets.
