I had 3 interviews over the course of 2 weeks. The first was a 30 minute phone interview with a recruiter, where we mostly discussed how my past experience related to the position and what kind of qualifications I had.
Next I went in for an interview and was there about 2.5 hours. I first met with a manager for the department who asked me all about my background. She started with my education, asking why I chose my major and what my favorite classes were (which I felt was odd, being that it's been almost 10 years since I graduated), and then she went through each job to ask about my responsibilities, what I liked/disliked, what were challenges, how my supervisor would describe me, etc. After that the director of the department came in and we had a more open conversation and dialog about my qualifications and background and how I might fit at the company. This was the time to ask any and all questions I had about the job.
For the 3rd part, I came in for a 'day in the life.' I was given a work project (reading and summarizing a report, finding people in the media I could pitch it to and then writing the email pitches), got to meet with a couple employees very briefly and then had a debrief with the managers and director of the department.
I thought it was so great that SA does the day in the life, because this was an opportunity for me to see that it was not the right fit for me. I expressed some doubt about my fit here and they ultimately ended up choosing another candidate, which I was happy about. I think it could be a great fit for the right person, this just wasn't right for me.
