I had one behavioral interview with the HM. After that, they scheduled four technical interviews with various members of the team - behavioral, data cleaning, statistics, and a collaborative coding interview. I believe there was one more non-technical interview after, had I made it to the final stage.

Beacon has a long, scripted interview process, including questions about data management, statistics, pair programming, and culture/values. Everyone was very nice and the questions were quite easy for me, so I did very well.
