Two rounds of interviews. All were pretty easy and questions were focus at the specific job at hand. The people seemed pleasant and pretty knowledgeable. I brought in work of specific projects I've handled and have more experience than necessary for the role. I could handle this role in my sleep. There was not a single difficult question or topic about the responsibilties. Even though I thought it went well, I was not offered the position. HR would not/could not provide any feedback as to why. The position is still listed on siteboards 3 months later.
