1) Generational stereotyping is for idiots.
2) This isn’t the first time the practice of bringing parents to a job interview has made the news. I first saw references to it at least 20 years ago.
I have never heard of such a thing.
I have interviewed some really dumb people for high-tech jobs, but never in 40+ years have I had to deal with parents either before, during or after an interview...........
