No. I strongly disagree with it.
In one of my interviews, there was a girl in our group whose father was one of the interviewers (I kid you not) - Obviously, he didn't interview her but he did interview other people in our group (and we had to be careful about what we said about him). But this girl was the most arrogant, snobbish, and rude person ever - if I was an adcom and saw her behave the way she did, I would never allow her to be admitted into medical school (no matter how good her GPA or MCAT was).. simply because there was no way I could fathom this girl being empathetic towards anyone.
Many people are rude but they are usually able to hide or mask this during interviews, and can behave properly for a couple of hours. But this girl didn't even bother. And I think part of it was because she knew she would be guaranteed acceptance (because her father was one of the big guys there) - so she didn't even bother feigning humility. This really bothered me.
(And, yes, I do know that one personal experience does not really provide support nor opposition to this... but I'd be against this even if it was not for my experience)
