I had a great but brief 30 minutes screen with HR. They very quickly decided they wanted me to come in for a 4 person 5-hour interview. I had plenty of time to prepare. The 4 people were friendly, asked good questions, let me ask most of my questions. 2 of the people were very rushed. They didn't make me feel very important. I asked if there were any reasons whatsoever that I would not be considered for the next round, and all interviewers "couldn't think of any." I had good feelings about the interview and expected to be called for the "final." The very next day, HR called and told me they liked me but wanted someone with a particular industry experience. This had never come up as an issue before, and the interviewers even seemed to downplay it. I do not currently have good feelings about the company doing this to me and taking me away from other activities related to my job search. They essentially wasted 2 weeks of my time.
