There were two interviews, one group and one individual. They both had a panel of interviewers and were about an hour long. Mostly asked interviewees questions, and didn't leave as much time for interviewees to ask questions.

Since this ws for a fellowship, I went through 2 interviews. One was virtual and with the assistant director of the fellowship and the 2nd was in person and i interview with a panel of leaders of the social work fellow: directors and socials workers who served as supervisors. It was pretty intimation so I would recommend calling any anxiety and being well prepared.
