Data Scientist Interview

Nov 16, 2020

Anonymous employee

Accepted offer

Positive experience

Average interview

Application

I applied online. I interviewed at Wayfair (Boston, MA) in Nov 2020

Interview

Recruiters were very clear regarding timeline and next steps after each interview (3 steps: initial recruiter call, technical case study, final onsite over two days with behavioral and technical days). They give you some information about the technical case so you can prepare for it, which I found very helpful. Overall a very good experience.
