I had two rounds of interview, and each round of interview was composed with two part (either one case and one behavior style interview, or two cases interviewed by different people)..... There were both quantitative and qualitative styled questions.
Applied through college. Two rounds of interviews: first via video conference, second at Wayfair HQ. Strategy cases and personal questions in both rounds, with additional Excel exercise in second round.
I applied online. The process took 3 weeks. I interviewed at Wayfair
Interview
Interviews were all behavioral you until the final round. Final round was 3 interviews back to back and then a live case study that lasted about 30 mins. Interviewers we're all very conversational and laid back, with few technical questions asked outside of the case study portion.
