Applied online and received a call back from a recruiter within about two weeks. There was an initial online coding interview and another call with the recruiter. The onsite was schedule about month later and was an all-day affair with a series of interviews with different members of the team, including a one-on-one with the team lead, then technical interviews on on data science methods and causal inference, software engineering, basic probability (like coin flipping problems), and data exploration.
