The interview process is long but well structured and recruiters are helpful. I had a take-home technical and a virtual onsite with live coding and stats questions. One thing that is a little strange is that the process is standardized for all data scientists so questions were irrelevant to the role I was applying for and I didn't interview with many people from the specific team.
