After initial contact with recruiter I was scheduled for two, thirty minute Skype interviews with a data and senior data scientist. The first interviewer asked mostly technical questions and the second asked mostly machine learning specific questions. I got a decision within a week.

Took an initial data science challenge. Then, after reviewed, interviewed by the hiring manager and a couple of data scientists/engineers on the team. The whole interview process was 2 hours with 4 sessions, and each session was about 30 minutes. The whole process took about 3 weeks (challenge review ~1 week, interview and decision ~2 weeks).
