First round - take-home assignment. I spent an afternoon on this and submitted my code and write-up. Questions were very open-ended and expectations somewhat unclear. Second round - 30 minutes video interview, in which I went over the assignment and my findings. I didn't get the time to ask questions or get any specific feedback about my take-home. Third round - video interview, 3 rounds. This include a management-consulting-style case interview that took me by surprise. I wished there was a chance for me to learn more about the role earlier in the process. It felt very much like a one-way evaluation. Haven't heard back from them yet and not sure if I've been ghosted.
