My last interview was with some large US corporation. I had scheduled the first interview with their tech lead in one of the departments. Interview started on time, we managed to say hello to each other, then something bizarre happened. I think the tech lead thought he has lost the connection, but I could see him and hear him clearly. Suddenly he started shouting, swearing and then he violently swept things off his desk and that's when the interview was cut off. I got a call an hour later that they have "technical issues" and the interview will be rescheduled. Three days later I got an email that I didn't pass the interview that I didn't really have in the first place. That was quite funny actually.
