Her social media, before it was deleted, showed that she did an internship at her father's firm, which didn't go well apparently.
It also showed that her father hired a service that helps young people get into elite universities, and IIRC, the cost was $50,000.
That's a lot of pressure and she really wanted to get into Stanford...but didn't. There were posts about that on reddit as well, at one point.
She did want to keep up with her sport (rowing) and UC Berkeley let her be a walk-on, but I also suspect she didn't want to be living at home. I can't imagine that kind of pressure from my parents to go to an Ivy or to Stanford...
