There was a phone interview, including general questions, a coding exercise and a brainteaser/analytical exercise.
There was a homework assignment analyzing sample data and creating a presentation on my findings, which I subsequently presented to the team.
The final round of interviews was a virtual onsite round, featuring 4 separate sessions of collaboration on an analysis, a statistics session, a management discussion and a second/final brainteaser/analytical exercise.
The entire process took about 1 month, including the time working on the Homework Assignment.
