The most difficult question I encountered was when the hiring manager emphasized after that we had already thoroughly discussed expectations, roles, duties, and the such when we didn't. How are you supposed to answer or respond to a question which describes a situation that hasn't occurred yet? You have to be able to dance without lying - some managers, senior managers, and directors likes this - they are more interested in ending a meeting 'on a positive note' or with a good feeling than they are in actually addressing topics.
