I applied online. The process took 1 week. I interviewed at Wayfair (Boston, MA) in Dec 2017
Interview
It was a series of behavioral questions and data oriented questions. It was structured in a way that the interviewer would give a set of set questions ("ok next question") and then left time at the end for any questions you will have.
Interview questions [1]
Question 1
