The process was long, the interviewers were mostly professional. An upfront tech screen followed by 2 case interviews (1 technical and 1 business). The final onsite had 3 interviews with lead data scientists. To be honest, I did not think very much of the final round, which was, for a lack of better expression, weird. I did not feel like they asked important data science questions and nor did I feel like they could accurately gauge or cared to gauge a candidate's caliber. I sat down with one who went through my hitherto unread resume with me, awkwardly, focusing on the wrong things. Another interviewer was tired from flying in on a red-eye, and did not seem to care about what I was saying, and claimed he was hungry during the interview and was dying to get to his lunch. I left the interview feeling like it was not a culture fit and I wasn't convinced they were doing interesting work.
