After not receiving a call from him at our scheduled time, I emailed him. He responded three days later telling me that he had called in sick the day he was supposed to call me and asked for my availability in the next few days. I gave him my availability, and never heard back until he just called me out of the blue. It was fine that time, but would have been very annoying if my availability had changed.
We talked for a bit and he said that he wanted to get me in touch with a startup company that he thought had a position that would be a good fit for me - same deal, I gave him my times and received no confirmation until the company called me one afternoon.
A little bit into the phone call it became apparent that he had told them I was open to permanent positions despite me making it very clear to him I was only looking for internships.
Great.
