Wayfair Analyst interview questions

I found the interview process unnecessarily long. I interviewed with 7 different people over the course of 3 months for an Analyst position. I applied to one role specifically and then halfway through the application process was told there was another role that had recently opened up and I was being considered for both. Additionally, after the final round I received an email regarding the candidacy. After such a long process it was frustrating to receive an email and no practical feedback.
