Adobe interview questions

I applied online. I got two rounds, one by phone and another on campus. First round, 2 calls, second round which happened after a few weeks, was 4-5 interviews in one day. Overall interviews were amazing. I really liked talking to everyone on the team and was quite excited about the opportunity. A week later the recruiter told me everyone liked talking to me and asked when I could join the team. Needless to say, it got me excited. Two weeks later when I didn't hear back anything from the recruiter I emailed them, only to hear that they were not extending the offer anymore. It was almost like extending an offer and rescinding it for no apparent reason. No feedback or reason was ever given and the recruiter refused to respond further.
