I had a phone interview and then was invited for a job talk. During the visitation day, I then had in-person meetings with faculty. Finally, I was taken out to dinner by a few relevant faculty. It was much like a job talk for a normal faculty position, perhaps with fewer professors in the audience.

two rounds of phone call, ask questions about past research projects. I talked about the latest research in the literature and then say I will plan my projects in such a way. The interviewer asks about the time complexity and work loan I will contribute.
