I applied through an employee referral. I interviewed at Wayfair (Boston, MA) in Jul 2017
Interview
3 rounds. 1st round is a basic HR round. The recruiter is very nice and more than an interview round it is about getting to know about the company. The second round consisted of some tricky data science questions regarding resume projects and a marketing case study (depends on which employee is taking your interview). The third round is on site consisting of many rounds talking to people from various fields at Wayfair. For me there were 2 case study rounds and 1 coding round.

Technical Interview on SQL and Python. Makes you program a machine learning model and write intermediate SQL commands. Overall, not too difficult, and it takes roughly 75 minutes. I would suggest praticing on Hackerrank
Very average interview where the questions were ambiguous. It was very ambiguity. And not clear on the requirement. So in short not difficult. Hard to say if anyone should interview for this company
