Interviewer asked technical questions, but demonstrated limited understanding of the questions he asked. For example, after I talked about the work I had done with REST services, he asked, with apparent uncertainty, whether they used HTTP or some other protocol. I was consequently unable to gain much insight into what the work would look like. When I mentioned that I had to move on a quick timeline because I had received an offer from another company (I had already scheduled this interview prior to beginning the other interview process), he got resentful and acted as if I had wasted his time.
