Aggregate Knowledge interview questions

The hiring manager needs to learn some manners and proper hiring etiqute. I was scheduled for a phone interview. Was called by the recruiter two minutes before the scheduled time saying that manager was no longer available. Was rescheduled. The hiring manager called twenty minutes late. Said that were looking for a skill, which was not in the job description at all, and as I was in the middle of describing my background/skills, said that I was not a fit and hung up on me. The whole interview lasted 2.5 minutes. This was the worst experience I've had with a hiring manager. Even if I was a fit, would never want to work for someone who is so disrespectful of her potential employees.
