I have something to add from the virtual interview trail:
At one of the schools I interviewed at, a member of the admissions staff had a knack for telling "dad" jokes between presentations. Real corny stuff, but since we were all polite and hyper-attentive applicants, each one got a chuckle or a response out of most of the 40-odd screens in the zoom meeting. After maybe the second or third joke an applicant unmutes and says, "ooh I got a good one!" Still, everyone is all smiles and the admissions guy says okay go for it.
The interviewee then tells an extremely off color joke with some less-than-PC language. Think "a hooker walks into a bar" kind of thing.
Stunned silence. No laughter, I can't remember if the admissions person said anything more than "...alright then."
Thankfully another applicant immediately jumped in and told an innocent groaner of a pun, and boom, all hoots and hollers again.
