First-round phone interview with HR. Pretty easy. Answered questions about my background. Second-round virtual interview with the teams. 5 interviews last about 2 hours. Everyone was very nice. Asked questions about my past SAS projects.

Started with some general background questions, then a more senior employee drilled me on statistical topics and terms, and then a SAS programming challenge before a wrap-up with HR. Overall, everyone was friendly and helpful but I didn't get the sense that they really wanted to be there.
