> EDIT: Maybe she was going to be at burning man with her mom eitherway. She just decided to get some more business oriented clothes for when she would hang with her new work mates. That makes sense.

How did that happen? "You're going to the same event as me, your interviewer? We should totally hang out there!" maybe?

> But now it makes zero sense for the article to mention the burning man story.

Which interviewer suggests (during the interview!) to meet up a week later in private at some event? One that is trying to be professional?

It shows he wasn't just using his position to make suggestions, but taking it one step further and planning things. During the interview.

In a story about culture by management towards sexual harassment, it makes a ton of sense to include this story.
