The interview was over the phone, which was set up by a recruiter. I had to be ready like I would have to be for a normal interview. The interview took 5 to 10 minutes. Once the interviewer realized that he could not get the kind of proprietary information he wanted from me ( based on something he saw in my resume which interested him ), he ended the interview quickly. In other words, he was pretending to interview me for a job, but was he was really trying to do was steal proprietary information from another company through me.
