HR Call, HackerRank test (mostly pandas numpy and sklearn), First round case (Cassey business case and technical case) then final round (technical case x 3). Cases are a mix of business and data science (although much more on the data science honestly).

First round case:
Technical case with current Data Scientist. Problem was around creating a model to help a customer with marketing strategy. Great conversation and really smart interviewer.
Final round:
First case was about having a restaurant chain as a client. The client wants to figure out how to maximize spending from customers.
Second case: a bunch of questions on statistics, SQL, etc. Interviewer came off as aggressive and arrogant, would just shoot questions at you one after the other.
Third case: Interesting case on bank fraud and how to deal with unreliable data. Interviewer seemed completely uninterested in the interview, to the extent he was looking at his phone, found it very disrespectful and unprofessional.
HR is really supportive and helpful throughout the entire interview process. But, 2/4 (might not be a representative sample?) of the data scientists seemed very disrespectful and unprofessional.

Coding challenge, then soft skills which i did not get to. Coding challenge was online timed in a third party tool. Not very hard but needed more time and didnt move quick enough.
