Longest interview process I have ever been part of. Took two months and 7 rounds not including the calls with the recruiter. They asked me to write an entire training document for junior data scientists as a communication interview, instead of a sample page or two which feels like taking advantage of a job seeker without pay. In depth one hour rounds on coding, machine learning trivia, case study, behavioral. No phone call to discuss the feedback at the end of the process.
