Now that I think about it, I bet you could put together a pretty successful YouTube series of messing with zoom interviews in ways just like this. Get someone's identical twin to join the call and make them fight over who's the real one. Bring time travel into it. Make outlandish demands of the interviewer to prove that they're not a Zorblaxian spy.
Not Zoom interviews, but there are Youtube videos of people messing up with other people on Omegle, with a fake skip screen. From the point of view of the pranked, what happens is they get to someone that ends up skipping them, get a different person, and the previous person shows up in the background or something.
