He assured me that it WILL be addressed with the two of them. This was unacceptable, and he said they're kind of off on their own there, so the behavior could have been going on for a while. No applicants had informed them of these issues before. He's calling other applicants that ultimately didn't accept the job there.
I was offered another location, but I think the other propect is looking good, so I told him that there was something else in the works. He asked me to call him if the situation changed.
Professional to the end. Too bad their dealership hadn't been that way.
