One must not forget that cheaters are now everyone, and it's likely you gonna be interviewed by a cheater. I've seen this multiple times already, recent is Meta interview ~8 months ago. Very low quality interviewer - complained about bug in the code, while there was no bug. Can't keep the conversation going, the same for system design - poor guy didn't even want to listen, and was pretty much rude.

I would say that if it wasn't a pattern. So let's not pretend they're not cheaters. Call them out.
