Wayfair Data Scientist interview questions

Got an interview invitation email 23hours before the assigned time. Email said I need to confirm my availability prior to 24hours the interview time. Sent email about this weired case an d had no answer. Anyway just had the interview through google hangout. Behavioral questions then case question.

This was a pretty standard interview. I was asked about my background and then walked through a problem to test my analytical skills. This was over Google hangouts. The whole process took about 1 hour.
