Had a first round interview with recruiter and a second round interview with senior manager (probably the hiring manager). It included a case study that I did not do so well on, so I did not move on.
Interview questions [1]
Question 1
They asked me some behavioral questions before moving onto the case.
I applied through an employee referral. I interviewed at Wayfair (Boston, MA) in Jun 2017
Interview
This was the in-person interview (3rd round), which was preceded by a recruiter screen and phone interview with a manager. There were five sessions, three of them with 2 interviewers, and two included case studies (60 and 90 min long).

Question 1
I was presented with a 9-step procedure to forecast unit sales based on the previous 12 weeks and the history over the past two years, and a general notion that it combines a static average, a linear trend, and a function modeling seasonality. I was given 25 mins to come up with explanations what each step did.
You are provided with a simple model of the success of a marketing campaign from clicking an add through making an actual purchase, and need to explain the key metrics for each stage. The model is then applied to compare profit versus cost for two scenarios, where in one of them the cost is higher but also the customer willingness to provide their email (one of the steps is capturing their email). For that case, you need to calculate the click-through rate to break even, and then compare that click-through to the initial (base) scenario
