Submitted my resume during campus PhD talk. I was shortlisted for a one on one interview on campus. Was asked general questions about research and behavioral questions. after the interview i was told that i would be invited for another interview. Got an invite to go for onsite interview. I went for the onsite interview after 2 weeks.

Interview took from 9:00am to 4:00pm. 1:1 interviews. Most of the questions where behavioral questions and about your research at school. They were very kind and make the interviews feel as a casual conversation. Be prepare for a lot of behavioral questions and questions about your research.
