I had an initial interview with the hiring manager that went very well. I then had several interviews with HR and members of the team, all voted to move me forward and so I met with the hiring manager again. It was a brief meeting, to prepare to meet with even more people there. I was excited about the meeting but unfortunately he seemed to be tired, in a bad mood and it was an awkward meeting. He cancelled the subsequent meetings and that was it. I've never had a follow up interview go so poorly after so many positive ones and I received no feedback, other than they decided to go with someone else. It was a surprising turn of events, but given the circumstances, I'm glad I didn't get the job.
