Contacted after I signed up for Indeed's Prime recruiting service. Had a homework assignment analyzing a dataset, then a very easy phone screen, half programming, half data science questions. Finally, an in person interview: this had a programming session with an interviewer, a lengthier individual programming assignment, a data science session (pretty much the same questions as the phone screen), and a statistics session. The in-person interview was much harder than the phone screen, but still easier than other interviews I've had. All the programming was in Python. They were very fast getting through the whole process, which was nice. I was worried about work/life balance here so didn't pursue the opportunity.
