I applied through college or university. I interviewed at Wayfair
Interview
The interview consisted of 1 behavioral and 2 case based interviews, each 45 minutes long. The behavioral interview was mainly about resume and past experiences in data science. The case based interviews presented you with a dataset and a problem and asked questions that basically prompted you to explain the business rationale for different features as well as the modeling approach you would take.

Question 1
Why do you think (given variable) would be helpful to have from a business perspective? What features would be helpful to predict (said variable)?
I applied online. The process took 3 weeks. I interviewed at Wayfair in Nov 2016
Interview
2 phone calls, first with a recruiter and the next with a member of the team. The questions were fair and the discussion was informative. Most of the questions about my previous experience were simply to see if I could explain something technical in a way that others could understand. Not a lot of deep question on specific machine learning algorithms. I had other questions for the recruiter and she was always quick to get back to me.
Afterwards I submitted a code sample and heard back a few days later to schedule a time to meet the team in person. 3 cases with current data scientists and a few one-on-one interviews with management. The cases typically presented some snippet of data alongside some questions about how to approach making a prediction model of some kind. The questions were pretty open ended. They were more interested in seeing how I approached the problem and if I could collaborate well in a group setting.
I was contacted a recruiter, had a phone call with basic introduction. The requirement was immediate and hence i was told to contact some other recruiter who would be interviewing for non-imediate requirements. Didn't hear back from anyone inspite of asking politely for the next steps.
