Total waste of time! An incredibly disrespectful experience.
Interviewers were unprepared, arrived late, left early due to double-scheduling over the interview, asked poorly written questions, and then failed to listen to my responses to their questions.
For example, one interviewer obviously wasn't listening to my answer. As soon as I finished answering, he would ask the question again - i.e. what made you leave your last job? Why are you looking for a new role?
Also, I had 3 interviewers actually do work during the interview - not type out our interview notes, but web browsing or other activities. I could see the screen reflected in their glasses and via other clues. SO RUDE!
This happened not only in the final round but also in the earlier calls.
