Went in for several rounds of interviews. The first round involved a manager hogging the entire interview process talking about himself. But apparently he enjoyed it, he brought me back to meet his boss. His boss came across as very enthusiastic and said he wanted to bring me back for me for 1 or 2 more rounds (5 more people). He completely changed his mind and decided in the following few days that I was a horrible fit. Unsure what happened between the great interview and the "No" decision.
