Wayfair Data Scientist interview questions

I was contacted by a third party recruiter about this job, and then he connected me with a recruiter at Wayfair. Then I talked to Wayfair's recruiter about compensation expectations and he told me about Wayfair. Then I had a phone interview with a senior data scientist. After that they scheduled an on-site interview with me. I had four sessions with 5 people. One was behavioral with simple case study. Second and third ones were more difficult case studies. And the last one was simple coding question and they asked me about what I do at my current job. Overall, the case studies we're interesting and difficult, but I liked talking to them.
