Thanks for all the encouragement, everyone.
Had my interview this morning. Very basic, very lighthearted chat with Larry, Richard, and Henry. Richard congratulated me on making it this far, and said no decisions had been made. Then Larry interjected and said that a ton of decisions had been made--they'd cut most of the applications down to their top choices, and now they had to cut a few more.
The rest of the interview was tailored pretty exclusively to me and my background as a writer, but it did boil down to why I chose Stark and where I'd ideally be in the future. They seemed pleased that I had a definite direction in mind, but who knows.
At the end, they asked me if I had any questions and that was it. They said I had to sweat it out a few more days, and that they'll have the decisions next week as expected.
In all, very casual, polite, and humorous exchange. It felt like they were looking for some minor clarifications on questions that arose on the app, and also like they're going through their list to make sure we aren't total duds.
Again, this was just my impression. Now, it's back to waiting for a week.
