Total 5 rounds. 1) HR Screening (basic team overview and questions about background). 2) 2 separate interviews - one focusing more behaviors (data story), another on technical (given a dataset, asked questions about my codes). 3) Stats & probability (applications & concept). 4) Data visualization (viz practices, 1 hypothetical case question, more behaviorals). 5) Strategy (case studies, more behavioral question about data & curveball questions) - come prepared, calm and confident.
Everyone I met has been mostly friendly throughout the process, it's a VERY intensive process (imo an overkill), but the forgiving part is they don't seem to be looking for perfection. Since it's such a long process, some behavioral questions asked would be repeated.
