Welcome to your interview.
The question is on your right: Investigate Forecast Accuracy Drop. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
Our forecast accuracy for bulky furniture items in the Northeast region dropped by 15% last month at Wayfair. Walk me through how you would investigate the root cause.
