The interview process was lengthy. It started with a phone interview with 2 data scientists that was mostly knowledge-based questions. After that was a data set challenge where you have to present your findings to 2 other data scientists and expect follow up questions. Last was the on-site where there were one data exercise interview and one behavioral interview. You'll also have to make another presentation about a past analytical project to the entire team. HR was quick to respond if you've made it to the next step but awfully slow at scheduling. It would take weeks and was frustrating since I was also scheduling other interviews. For those with a CS background, this is a heavy math/stats role so don't expect much programming.
