The other round was to know the team members and they asked me about how would you calculate the number of coffees is being sold from Starbucks in Atlanta. They wanted me to think loudly basically! The data science position that I was being interviewed for was in price optimization so that's why they wanted me to have a good understanding of customers' needs. The last round was with the director of the department and he just wanted to know me better and asked me really simple questions of why you chose Delta, what are the challenges that you think you would have...
