I went through 3 rounds of interviews spread over nearly two months. The first round was telephonic with only technical questions asked. The second and third were a managerial rounds. At the end of the last round, I was told I would be contacted by HR. I wasn't contacted. After about a month after the last interview, when I contacted HR, I received a generic email response that the job I had applied for was no longer available! Having given my time for 3 rounds of interviews, for one of which I had to physically go to their office, the least I expected was a professional response.
