First round: 2 back o back interviews, standard cases + behavioral. Overall straightforward, need basic math skills but nothing crazy. Super day is similar (case + behavioral for each interview), with day full of company presentations and lunch / dinner in Boston.

Very easy to practice, very similar to their practice case. I followed a similar outline to the funnel they used for market sizing, at least. Most graphs they show are very interpretable and very epidemiology-dependent.
