1 HR screening -very straightforward
First Round: 1 Statistical case study (easy)
Second Round: 1 Business case study (straightforward)
Final Round: 1 behavioral interview, 1 business/stats case study (harder)
Over all nothing crazy or unexpected. Was suprised to not receive an offer as I was technical skill-wise over qualified. The recruiter was very nice and told me their feedback, which was that my answers on the business case study was not structured well.
