Aetna/CVS Lead Data Scientist - final interview round

I have moved to the final round for a Lead DS role at Aetna/CVS. The role is in the Analytics and Behavior change org. Can anyone share some details on what to expect in the final round of interviews? I'll be having 4 interviews, 45 mins each on Webex. Any pointers will be helpful! #datascience #interview #aetna #dataanalytics
