Entretien
Everyone involved was great. First I had 3 phone interviews, and the last two included programming online, where they could watch. After, they flew me out, and 5 people interviewed me for about 3.5 hours straight in person. They had the standard statistics/SQL/programming questions for the data scientist position and I really screwed up on a simple probability question. Despite that, they made me an offer within 3 days.

Question 1
I signed an NDA, so I can't give much details, but one interviewer asked me a very open ended question that involved how I would create/design/implement a certain algorithm from start to end.

After applying, I had a behavioural phone screen with a recruiter, followed by a technical phone screen with a data scientist (who seemed to be doing interviews exclusively now). I was told the next steps were a phone call with business stakeholders, followed by an on-site interview day.
