Reasons for joining: 70% just needed a job, 20% location (silicon valley - wanted to be in tech ecosystem), 10% was combo of: I was told it's a small, entrepreneurial team with undefined remit (so opportunities to forge own path - turned out to be true) and it was impressive in many non-technical ways (company mission, campus, resources, etc)

And no reasons relating to technical or data science know-how on the part of the team/company ;) I already knew coming in that the industry is technologically backwards (big healthcare co)
