Half of the questions were essentially questioning my knowledge of material I have a Ph.D. in and education rather than my skillset. The topic I was asked to give a demo talk on was information that would never be discussed in that way if it were taught in a classroom. I was also asked questions about topics that were not mentioned in the job description and were outside the area of expertise of the position that was posted. They didn't let me ask questions at the end. I assume they had someone specific in mind for this job but the whole experience felt like a waste of time.
