I just had one of the funniest interviews I have ever had:
The "hiring manager" called me after a very professional phone screen that took place a few days earlier at a large well known rapidly growing company.
He called late and admitted it was due to dialing the wrong number multiple times. He had no good questions for me and he was fumbling trying to think of them. He never asked me for questions and the whole phone interview lasted 8 minutes. It was obvious he couldn't think of any more questions so he told me to expect a call from HR soon.
The best I could do at the time was to explain my experience in a nutshell without rambling on.
Is it possible to communicate my qualifications for the position when the interviewer is completely unprepared? Should I take control of the interview of myself by answering questions that he should have asked?
This last question would be speculation but do people really get hired from interviews like that?
