I wonder about the meaning of "Joint Interview". I'm reading an article about Trump and I found this term. I've looked it up, but I still don't know whether the expression can be used like "interview" or as an interview with someone else answering the questions. I leave you the paragraph:
The barrage of inflammatory comments in joint interviews published Sunday and Monday in Britain and Germany elicited alarm and outrage in Europe, even as Ms. Merkel dryly characterized Mr. Trump’s positions as nothing new.
