Indegene Web Program Manager interview questions

There seems to be a pattern with this company. I went through 4 rounds of interviews and a hr interview, all went well and positive feedback. During this whole process which took over a month I was clear that I did not have specific exp in a cms platform that they use. This seem to be not a problem since I have exp with other cms platforms. After the last interview they went dark for about two weeks. After a few emails and some text they finally got back to me and told me they wanted someone who had exp in that cms platform. Thats fair enough reqs are important. But what is not fair is making one go through so many rounds send me benefit information talk about salary reqs tell me that you are looking forward to working with me then decide I dont have the skill you are looking for. Not very professional.
