Wayfair Business Intelligence Analyst interview questions

Was not expecting the quantitative case interview over the phone. There were no questions relating to BI or database structure/SQL language.

The interview started with some general behavioral questions about your resume and experience, which took around 15 minutes. Then it was a small case interview and the case is about the consequences of changing a small feature of their website. You are supposed to think of some metrics and analysis to evaluate the efficiency of this change.
