Wayfair Data Science interview questions

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.
