The interview is between Sam and Anne. I have no clue why the GP listed Anne's sister and ex in their comment and used that as evidence of some kind of lack of diversity. If you listed me, my sister and my ex and some guy who happened to interview me, you could make similar assertions of lack of diversity:

"Look, Doreen is a former military wife whose father was also career military. Her sister had the same father and ended up working for the US government as well, though not as a military member. And the person interviewing Doreen knows her socially because (insert connection). See? See? It's like a club or something!"

As far as I can tell, the list is completely cherry picked and I have no idea what the point of it was. Which is why I asked, which is looking like a mistake.
