Wayfair Business Analyst interview questions

First round interview, but pretty formal-Directly start with, no behavior questions, three cases, two are testing your analytic skills and one is a math problem. Total time is about 1 hour long

Applied on school website, and got the first round of video interview. The second round consisted of one behavioral and two case interviews. The case interviews were similar to each other but focused on different lines of business in Wayfair. The behavioral interview was really hard because the interviewer asked many unexpected and tricky questions. Overall, the company culture seems pretty good. People seem nice, and the office has a start-up feel with open desks. HR said I wold hear back the result in a week.
