Wayfair Business Intelligence Analyst interview questions

Applied on the Wayfair Careers website, received Codility challenge ~10d later. Easy SQL/Python question + two business analysis problem. After that had a 1-hr Google Hangouts interview with one of the managers. Was asked about resume + a short conversion rate calculation problem. Received onsite invite and a data set ~ one day later. 3-part super day during one of which you had to present your insights in the dataset.

The interview lasted for 1 hr (45 mins case studies ) 15 minutes for me to ask questions. The interviewer was friendly and was helping whenever I was stuck while solving the case study.
