I am still in the process. The very first response after my application was a codility challenge with 4 tasks: sql, easy algorithm, business logic question and analysis of excel spreadsheet. After that I was scheduled to have a phone call with a HR: nothing special, just walk through the resume. The next step is video interview with a business case and If I succeed with it - an on-site interview.
Interview questions [1]
Question 1
Codility: sql, algorithm in any language you choose, two open questions related to business logic and analysis of excel spreadsheet
I applied online. The process took 1 day. I interviewed at Wayfair (Boston, MA) in Sept 2019
Interview
First applied online, then an online assessment will be sent via email, then video interview, then on-site interview in their office. My suggestion is bringing your own food and water if you have on-site interview with them.
The entire process has been very smooth and procedural so far. My first round was a set of questions which had a time limit and I could do it at home. The second round was with a BI Analyst for which she asked a few questions and a case study.

Question 1
The case study was about physical catalog marketing. One of the questions was how to track the performance of such a campaign?
