North Coast Education Services interview questions

I applied with a resume and cover letter. In about a week, I was called by the manager. We had a brief conversation and was asked to come in for an interview. I showed up early, but he showed up about 30 minutes late, claiming that he had made a mistake in his calendar. He and I spoke for 15 minutes or so, largely consisting of him explaining what they do and what they would expect of me. Then I was left in the conference room for about 10 minutes or so. He brought another colleague in to speak with me and finally the people whom I would be working with closely. He said that he would call me with either an offer or a rejection. Four weeks later, I have not heard back, despite my making two follow up calls.
