I applied through university. The process took 2 weeks. I interviewed at Wayfair (Boston, MA) in Jan 2016
Interview
Submitted resume through school website. A phone screen. An on-site with two back-to-back with two interviewers each. The recruiter was very nice, responsive, and helpful in general, but I haven't heard back from them yet.
Sent a link to select a time to interview after I submitted an online application. 1hr45min. Mostly Excel/Google Sheets-based case study questions, some behavioral questions included. The interviewers were relatively amicable and friendly; took time to answer analytical questions and explain the case studies.
