A long process including a phone screen, homework assignment and on-site with 5 or 6 team members. The interview questions were a mix of behavioral and statistics questions, nothing too difficult if you have any sort of math/stats/economics background. A couple of the interviewers during the onsite were quite dismissive and rude, at one point one even asked "why did you even apply for this role?". Overall, a very long and discouraging process.
