Started with a 1-hour zoom interview and got an on-campus visit in 1-2 weeks. The campus visit was a day-long process where I met with 7-8 faculy. As part of the campus visit, I gave a 50-minute mock lecture.

Had to prep a 5 minute lecture than a 50 minute lecture. The 50 minute lecture was interrupted a lot by comments from professors that did not reflect the types of comments students would get. It was hard to manage the time effectively. I have heard that this is common, but it makes sense for an elite school. I would prepare not just for comments you think students would ask (they may or may not show up) but also for those that you think profs would have.
