First there was a Recruiter Human Resources phone screen, then a Hiring Manager interview, a panel with two to three other current data scientists, and a technical round. Pretty standard and straight forward.

Entretien
I had a recruiter phone screen, another phone screen with 2 DS's (included some easy live-coding on a shared screen), a homework assignment, and an on-site.
The on-site portion was a pretty typical interview for a Senior (or non-Junior) DS role. I was given a 'homework assignment' beforehand, and I walked the entire DS team through my solution - they asked about my method and quizzed me on what I thought the next steps would be.
The 1:1 interviews were the usual mix - algorithmic whiteboarding in Python, talking about Machine Learning projects, whiteboard probability problems, and talking to some of the DS's about their projects and how I would think about them.
Everybody I spoke to was extremely smart and very nice.
