Wayfair Category Associate interview questions

I interviewed with Wayfair several times. Each time I was rejected. I was scheduled for another interview. After an hour the person who set up the interview came back to me and said "this position is looking for a similar skill set from the other positions you interviewed for. So we are cancelling the interview. I was polite and asked where is the skill gap that was identified in the previous interviews that is missing? They said they weren't the person working on the position. I then asked how did you arrive at the conclusion that I had a skill gap and whose the best person to address it with? They would not answer after that. I found this process unprofessional that my resume grabbed their attention however they would not address any skill gaps.

Lets just say I am very disappointed in Wayfair. The recruiter reached out to me on LinkedIn to discuss a few open positions they wanted to place me in. I had a 30 min phone call with the recruiter, who then set up the initial case study interview. After the case study happened (I think I did well, but honestly received 0 feedback), I was told the position had internal interest and they have to interview all of them first. Fine by me, internal promoting is a great practice, but why are you wasting my time if you reached out to me. After another week and a half of waiting, the recruiter passed me off to another recruiter to see if another position was open. There were some other spots open, so the recruiter set up three additional interviews (2 behavioral, and 1 more case study) over the course of 3 separate days. After I finished the interviews, I was told to wait another week just to get a phone call saying everyone really liked meeting you but we are moving forward with other candidates. What baffles me is the fact that I didn't even apply for these positions, and they strung me along keeping my hopes high throughout the entire month and a half long process just to be told no.
