I had 5 interviews which they asked me tons of questions and then I didn't got selected for the role when I had enough experience and knowledge, then they sent me another email saying that the position was open again and I had to do one more interview, so I did and then they told me that the role changed so I won't be a good fit anymore so basically I lost 6 hours of life trying to arrange these interviews was very unprofessional and actually I started to be grateful to not have been selected I cannot imagine how would be inside of the company
