The first interview was a quick prescreen with an HR recruiter to find out things like interest, salary requirement, etc. The second interview was over the phone with the hiring manager. That lasted close to an hour. He explained the position, asked me questions he had, he asked questions feeding off my repsonses as well, and answered questions I had about the position. The conversation went well. The next interview was on-site where I first talked with an HR rep for 30 minutes and toured the building, then talked 30 minutes with the person I would be replacing, and then 30 minutes with the hiring manager. The recruiter asked basic questions focusing on culture fit. The person I was replacing asked questions about how I would do or did do certain things related to the position. The hiring manager largely just went over things we had already talked about.
