First interview is behavioural, then you get three day to do a take home science assessment and take home case study. The science assessment is writing a 1 page summary of 3 different scientific articles and the case study is creating a presentation/recommendation for a client.

It is a rather extensive interview process, around seven steps and will take around a few months so be prepared. Rather light HR first step with a take home double assignment, be warned that you won't get any feedback otherwise and it is rather cold in that aspect.
