Wayfair Senior Category Manager interview questions

A recruiter reached out to me via LinkedIn and wanted to set up an informational interview via phone call. We set up a mutually agreed upon time and when the meeting came, no one called. I promptly emailed the recruiter confirming our time, and they responded that they had recently migrated to a new calendar system and my interview got lost on her old calendar. I get it, it happens, no biggie. The informational interview went fine, very standard. Fast forward to the second case study interview. It was set up by a different coordinator in HR and I gave my availability for four different dates with varying times. I received a calendar meeting from the coordinator to do a video Google Hangouts interview. I was to perform calculations live on Hangouts, but not permitted to use a calculator. There was no prompt to prepare, only general guidelines for the case study. My video interview time rolled around and I waited for 15+ minutes on the Google Hangout. Not one person participated or joined my meeting. I immediately emailed the recruiter and the meeting organizer and I received an automatic out-of-office reply. The coordinator wasn't even working that day. The recruiter replied to me and apologized and said that it was not a company standard, and they had a miscommunication with scheduling. I can understand one missed interview, but two is unacceptable. Especially when Wayfair initiated the process. I didn't know ghosting interviews was a thing until Wayfair!
