For my department, it was 1 on 1 with one of the professors. They asked me a several questions, talked about what they do, and explained what my responsibilities will be.
I worked at the BFS department. The interview really varies by manager, but the process was straightforward and supportive. We were asked to complete a design challenge and present it.
Had one interview that lasted about 30 minutes. Pretty basic questions regarding the position and my past experience. 2 interviewers who were both kind. Wanted to make the process easy for me.
