I applied through college or university. The process took 2 weeks. I interviewed at Wayfair in Feb 2019
Interview
The interview process consisted of an online technical case study and some basic questions about my past profile and a few technical questions. My first interview that was scheduled (online call) resulted in a no-show. It was later rescheduled to the following week.
The actual interview started with an in-depth discussion of one of the projects on my resume. Then a few technical questions in computer science and python. I was asked what several functions do in python which did not make sense to me as these are things that one can easily look up online and don't require any understanding of data science.
The last few minutes were a case interview based on a problem that they faced at the company

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
