This was the weirdest interview I've ever had. The layout was pretty standard (5 interviews with 1 or 2 employees, all about 30 minutes long). However, the interviews themselves sent off alarm bells. The first few interviews I got exceptionally basic statistics and CS questions that didn't pertain to much of anything. This being despite the fact a masters degree in statistics is required. For example, one interviewer asked me what the variance of a binomial distribution was, while another asked me how to convert a string to float in python. Additionally, I asked many employees what their most fulfilling projects have been and they all scoffed and said the projects just blended together, which doesn't give me faith that I'd enjoy this job.
