I did four interviews. Two of them, design&integration and product owner, lacked any constructive feedback. The interviewers read the questions from a list, took notes, and weren't able to answer any technical question from me. I got rejected because of my alleged lack of communication skills with non-technical stakeholders. I can only suppose that those two were the non-technical stakeholders, and that I had to somehow imagine I had to answer to technical question in a non-technical way. Mindblowing loss of time.
