Interview
The interview process begins with a take-home quantitative assessment, where you’ll work through real-world data modeling, statistical analysis, and probability problems within a three-day window. Candidates who demonstrate strong analytical rigor are then invited to a half-day, on-site interview featuring technical case studies, quantitative brainteasers, and behavioral discussions with team members and hiring managers.

First round with HR, then second round with a panel to solve a few coding problems. Did not make it past this round. However, the company was very much kinder than others I applied to and treated candidates respectfully and as humans.
