I applied through college or university. The process took 4 weeks. I interviewed at Wayfair (Boston, MA) in Oct 2019
Interview
First round was a quick online assessment with 1 coding problem and general ML questions. Second was a phone screen with a data scientist that involved discussion of a data science case study relevant to WayFair. Final round was an onsite interview in the Boston office that included a technical case study round, a behavioral round and a coding interview. I heard back from the recruiter next week that they decided to move forward with another candidate.
